[PATCH v3 0/1] Fix and improve zcrypt reply message checks

[Harald Freudenberger <freude@linux.ibm.com>]

Fix and improve zcrypt reply messages checks of type 6 - CCA and EP11
- and type 50 - ICA.

Changelog:
v1: Initial version
v2: Sashiko complained about not checking offset1/count1 at all if
    count2 for an CCA type6 reply is given. And a check like this was
    in place before the rework. So now offset1/count1 is always
    checked and only if count2 is non zero offset2/count2 is
    additionally checked.
v3: Again Sashiko had some complains which let to a broader review of
    the reply processing functions. Especially the zcrypt_type50.c
    functions convert_type80() and convert_response() got slight but
    significant improvements - and also a mysterious BUG_ON has been
    removed.
