CI: Selftest failures of s390 SHA3 and HMAC on next kernel

Hi Herbert,

in tonight's CI run the self-tests of the s390x kernel ciphers for SHA-3 and HMAC (with SHA-2) started to fail on the next kernel.
This must be something the came into the next kernel just recently (yesterday). It did not fail before tonight.

Affected modules: sha3_512_s390, sha3_256_s390, and hmac_s390.
Not affected are: sha512_s390 and sha1_s390.
sha256/sha224 no longer exist as module, probably due to the move to be a library now.
All SHA-2 digest self-tests pass, but strangely, the HMAC with SHA-2 self-tests fail....
