qcacmn: Stop ROC timer synchronously

Mc timer is used to initialize the p2p roc timer.
And the actual timer runs in the soft irq thread and
when the timer exipres it posts the message to mc thread.
Currently, qdf_mc_timer_stop is called to stop the timer.
It calls the del_timer internally to delete the timer.
del_timer() ensures that the given timer is not queued
to run anywhere in the system. But the callback may
be running on another CPU core can create race conditions.

So use del_timer_sync to delete the roc timer.
