ext4: fix error message when rejecting the default hash
Commit 985b67cd8639 ("ext4: filesystems without casefold feature cannot
be mounted with siphash") properly rejects volumes where
s_def_hash_version is set to DX_HASH_SIPHASH, but the check and the
error message should not look into casefold setup - a filesystem should
never have DX_HASH_SIPHASH as the default hash. Fix it and, since we
are there, move the check to ext4_hash_info_init.

be mounted with siphash")
