drivers: shs: Clear out pending core switch timers on cleanup
In case there is a burst of data beyond a threshold, the core switch
timer will try to schedule a worker once the timer expires.
While the pending work is cleaned up on timer expiry, the pending
timers itself are not cleared up.
As part of this change, the core switch module parameter is
reset on start of cleanup to ensure no more timers are configured
during the cleanup.
