qcacmn: trigger panic if completing tasks takes too long

Browse Source 
Trigger panic if it takes too long in completing
the tasks. And also modify the maximum retry count
if PANIC_ON_BUG is enabled to avoid false alarms.
It makes debug easier for tasklet stuck and schedule
latency related issues.
