Rajkumar Manoharan f6b4e4d476 ath9k: Fix locking issue during tx completion 
The received tx status of aggregated frame without BlockAck may
cause deaf state in AR5416 cards. So the driver does a reset to
recover. When this happens, we release the pcu_lock before doing
a reset as ath_rest acquires pcu_lock. This is ugly and also not
atomic. Fixing this addresses the TX DMA failure also.

ath_tx_complete_aggr can be called from different paths which
takes different variants of spin_lock. This patch also addresses
the following warning.

WARNING: at kernel/timer.c:1011 del_timer_sync+0x4e/0x50()
