scx_link_sched() carries each failure out of the locked section through err_msg and ret because scx_error() used to take scx_sched_lock and couldn't be called under it. That restriction is gone, so report each failure at the site it's detected and return directly. The scx_error() here claims the exit on the sched being linked, which has no descendants yet, and the locked propagation walk is deferred, so nothing reacquires scx_sched_lock inline.
