mei: stop the stall timer worker if not needed
The stall timer worker checks periodically if there is a stalled i/o transaction. The issue with the current implementation is that the timer is ticking also when there is no pending i/o transaction. This patch provides a simple change that prevents rescheduling of the delayed work when there is no pending i/o.
