crypto: s390/aes - drop redundant xts key check
xts_fallback_setkey() in xts_aes_set_key() will now enforce key size
rule in FIPS mode when setting up the fallback algorithm keys, which
makes the check in xts_aes_set_key() redundant or unreachable. So just
drop this check.
xts_fallback_setkey() now makes a key size check in xts_verify_key():
xts_fallback_setkey()
crypto_skcipher_setkey() [ skcipher_setkey_unaligned() ]
cipher->setkey() { .setkey = xts_setkey }
xts_setkey()
xts_verify_key()
