Fix the lock owner sanity checking during background thread boot.

Browse Source 
During boot, some mutexes are not initialized yet, plus there's no point taking
many mutexes while everything is covered by the global init lock, so the locking
assumptions in some functions (e.g. background_thread_enabled_set()) can't be
enforced.  Skip the lock owner check in this case.
