cnss2: Add code to address boot timer debug corner case

Browse source 
To handle corner case where mhi power on success and the boot
debug timer handler execution(i.e dumping register) runs parellel.
Even-though the timer is deleted as soon as mhi is powered on,
as this handler is still running it is armed again. Use
del_timer_sync which makes sure the timer is not queued and
the handler is not running upon its exit.
