KEYS: Fix an error code in request_master_key()

commit 57cb17e764ba0aaa169d07796acce54ccfbc6cae upstream.

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")
