media: cec-pin.c: don't zero work_pin_num_events in adap_enable
It's OK to keep the pending pin events when disabling or
enabling the 'adapter'. Zeroing this can cause a race condition
if this happens when the pin kthread is handling a pin event
and calls atomic_dec later, causing work_pin_num_events to become
negative.
Just leave pending events in the queue, they'll be read eventually.
