When loading encrypted-keys module, if the last check of aes_get_sizes() in init_encrypted() fails, the driver just returns an error without unregistering its key type. This results in the stale entry in the list. In addition to memory leaks, this leads to a kernel crash when registering a new key type later. This patch fixes the problem by swapping the calls of aes_get_sizes() and register_key_type(), and releasing resources properly at the error paths.
