Mohammed Shafi Shajakhan 5d9b6f2639 ath9k: Fix a crash in 2 WIRE btcoex chipsets 
Generic timers for BTCOEX functionality is applicable
only for 3 WIRE BTCOEX (and MCI) chipsets.
Hence btcoex->no_stomp_timer is allocated only 3 WIRE
btcoex chipsets and in all the other cases its NULL.
Make sure we stop the generic timer only if
'btcoex->hw_timer_enabled' is true(only if its up and
running)

Fixes the following crash
