Now that the ampdu_action callback can sleep,
we can use the mutex to properly protect the
aggregation data, and return useful errors if
they should happen.
Also, add some sleep and mutex debugging so
we won't call any of the functions that now
require being able to sleep and/or the mutex
to be held in an invalid context.

Reviewed RX descriptor functions against the HAL sources. Some minor changes:
- check size before making changes to the descriptor
- whitespace
- add comments about 5210 timestamps. this needs to be adressed later!
- FIFO overrun error only available on 5210
- rs_phyerr should not be OR'ed
- clear the whole ath5k_rx_status structure before using, instead of
zeroing specific fields.

Explicitly enable the usage of fallback rates for
the transmission of frames with rt61pci and rt73usb hardware.
Note that for txdone reporting, only rt61pci is capable of
reporting the fallback rates, for USB it is not possible
to determine the number of retries. However the device will
use the fallback rates, so it might still help in the performance.

In some corner cases the reported tx rates/retries didn't match the really
used ones.
The hardware lowers the tx rate on each consecutive retry by 1 (but won't
fall back from MCS to legacy rates) _until_ it reaches the lowest one.
In case the frame wasn't sent succesful the number of retries is 7 and if
a rate index <7 was used the previous code reported negative rate indexes
which were then ignored by the rate control algorithm and mac80211.
Instead, report the remaining number of retries to have happened with
the lowest rate (index 0). This should give the rate control algorithm
slightly more accurate information about the used tx rates/retries.

Set up max_rates and max_rate_tries with suitable values even if we do not
support the whole functionality.
As rt2800 has a global fallback table we cannot specify more then one tx rate
per frame but since the hw will try several different rates (based on the
fallback table) we should still initialize max_rates to the maximum number of
rates we are going to try. Otherwise mac80211 will truncate our reported tx
rates and the rc algortihm will end up with incorrect data choosing unsuitable
rates for tx.
This improves throughput on rt2800 devices considerable.

Currently rt2800pci will read TX_STA_FIFO until the previously read value
matches the current value. However, it is obvious that TX_STA_FIFO only
contains values that can easily be the same for multiple consecutive frames
(especially when communicating with only one other STA). Hence, we often
ended up with reading only the first entry and ignoring the rest.
One result was that when the TX_STA_FIFO contained multiple entires, only
the first one was read and properly handled while the others remained in the
tx queue.
Thus, drop this check but introduce a maximum number of reads. All legacy
drivers use the size of the tx ring as limit but state that the TX_STA_FIFO
has only 16 entries. So, let's just stick with the tx ring size for now.

IEEE80211_TX_CTL_MORE_FRAMES indicates that more frames are queued for tx
