ath9k: stop on rates with idx -1 in ath9k rate control's .tx_status
commit 2504a6423b9ab4c36df78227055995644de19edb upstream.
Rate control algorithms are supposed to stop processing when they
encounter a rate with the index -1. Checking for rate->count not being
zero is not enough.
Allowing a rate with negative index leads to memory corruption in
ath_debug_stat_rc().
One consequence of the bug is discussed at
https://bugzilla.redhat.com/show_bug.cgi?id=768639
