locks: don't call locks_release_private from locks_copy_lock
All callers of locks_copy_lock pass in a brand new file_lock struct, so there's no need to call locks_release_private on it. Replace that with a warning that fires in the event that we receive a target lock that doesn't look like it's properly initialized. Acked-by: J.
