s390/pai_crypto: Rename structure paicrypt_map to pai_map 

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.
Rename structure paicrypt_map to pai_map.
No functional change.
