appletalk: Set error code if register_snap_client failed

Browse Source 
commit c93ad1337a upstream.

If register_snap_client fails in atalk_init,
error code should be set, otherwise it will
triggers NULL pointer dereference while unloading
module.

Fixes: 9804501fa1 ("appletalk: Fix potential NULL pointer dereference in unregister_snap_client")
