Tony Krowiak 2f23256c0e s390/ap: fix error handling in __verify_queue_reservations() 
The AP bus's __verify_queue_reservations function increments the ref count
for the device driver passed in as a parameter, but fails to decrement it
before returning control to the caller. This will prevents any subsequent
removal of the module.
