ext4: improve error handling from ext4_dirhash()
commit 4b3cb1d108bfc2aebb0d7c8a52261a53cf7f5786 upstream.
The ext4_dirhash() will *almost* never fail, especially when the hash
tree feature was first introduced. However, with the addition of
support of encrypted, casefolded file names, that function can most
certainly fail today.
So make sure the callers of ext4_dirhash() properly check for
failures, and reflect the errors back up to their callers.
