[SRU][Bionic][PATCH 4/5] s390/zcrypt: remove unused functions and declarations

[Frank Heimes]

From: Harald Freudenberger <freude at linux.vnet.ibm.com>

BugLink: http://bugs.launchpad.net/bugs/1799184

The AP bus code is not available as kernel module any more.
There was some leftover code dealing with kernel module
exit which has been removed with this patch.
