net: fix network drivers ndo_start_xmit() return values
Fix up remaining drivers returning a magic or an errno value from their
ndo_start_xmit() functions that were missed in the first pass:
- isdn_net: missed conversion
- bpqether: missed conversion: skb is freed, so return NETDEV_TX_OK
- hp100: intention appears to be to resubmit skb once resources are
available, but due to no queue handling it is dropped for now.
- lapbether: skb is freed, so return NETDEV_TX_OK
