[patch 22/24] s390: CEX2A crt message length.
Undetected edge case for CRT messages to CEX2A caused length to be too short,
thus truncating the message. The solution was to check a different variable
which actually determines which key type is being used.
Increament version number in z90main.c to correct level of 1.3.3, fix
copyright year and add comment about bitlength limit of CEX2A.
