Subject: [PATCH v3 0/4] s390/crypto: Use -ENODEV instead of -EOPNOTSUPP

s390x crypto is one of the rare modules that returns -EOPNOTSUPP instead of
-ENODEV in case HW support is not available.

Convert to -ENODEV, so e.g., systemd's systemd-modules-load.service
ignores this error properly.

v2 -> v3:
- "s390/pkey: Use -ENODEV instead of -EOPNOTSUPP"
-- Also convert pkey_clr2protkey() as requested by Harald
- Add r-b's (thanks!)

v1 -> v2:
- Include
-- "s390/crypto: ghash: Use -ENODEV instead of -EOPNOTSUPP"
-- "s390/crypto: prng: Use -ENODEV instead of -EOPNOTSUPP"
-- "s390/crypto: sha: Use -ENODEV instead of -EOPNOTSUPP"
