s390/pai: fix sampling event removal for PMU device driver
In case of a sampling event, the PAI PMU device drivers need a
reference to this event. Currently to PMU device driver reference
is removed when a sampling event is destroyed. This may lead to
situations where the reference of the PMU device driver is removed
while being used by a different sampling event.
Reset the event reference pointer of the PMU device driver when
a sampling event is deleted and before the next one might be added.
