s390/pai_crypto: Add common pai_stop() function 



To support one common PAI PMU device driver which handles
both PMUs pai_crypto and pai_ext, use a common naming scheme
for structures and variables suitable for both device drivers.

Add a common usable function pai_stop() for the event on a CPU.
Call this common pai_stop() from paicrypt_del().
