fscrypt: introduce fscrypt_prepare_readdir()
The last remaining use of fscrypt_get_encryption_info() from filesystems
is for readdir (->iterate_shared()). Every other call is now in
fs/crypto/ as part of some other higher-level operation.
We need to add a new argument to fscrypt_get_encryption_info() to
indicate whether the encryption policy is allowed to be unrecognized or
not. Doing this is easier if we can work with high-level operations
rather than direct filesystem use of fscrypt_get_encryption_info().
So add a function fscrypt_prepare_readdir() which wraps the call to
fscrypt_get_encryption_info() for the readdir use case.
