fscrypt: check for appropriate use of DIRECT_KEY flag earlier
FSCRYPT_POLICY_FLAG_DIRECT_KEY is currently only allowed with Adiantum encryption. But FS_IOC_SET_ENCRYPTION_POLICY allowed it in combination with other encryption modes, and an error wasn't reported until later when the encrypted directory was actually used. Fix it to report the error earlier by validating the correct use of the DIRECT_KEY flag in fscrypt_supported_policy(), similar to how we validate the IV_INO_LBLK_64 flag.
