_cancel_timer and _cancel_timer_ex both were internally using del_timer,
and the issue was reported in bugzilla. I have given the reference of the
bugzilla in my patch in lkml.
I have changed the reference of del_timer_sync to del_timer in all places
which were in interrupt context, in some places it was not removed as
those were not in interrupt context.
