s390/pai_crypto: Rename paicrypt_copy() to pai_copy()

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 paicrypt_copy() to pai_copy() to indicate its common usage.
No functional change.
