This function has two callers and neither are able to handle a NULL
return. Really, -EINVAL is the correct thing return here anyway. This
fixes some static checker warnings like:
security/keys/encrypted-keys/encrypted.c:709 encrypted_key_decrypt()
error: uninitialized symbol 'master_key'.
Fixes: 7e70cb497850 ("keys: add new key-type encrypted")

Feel free to add by "Acked-by" on both this patch and Dan's other patch
"KEYS: Use memzero_explicit() for secret data".
