[PATCH] device-mapper multipath: Fix pg initialisation races
Prevent more than one priority group initialisation function from being
outstanding at once. Otherwise the completion functions interfere with each
other. Also, reloading the table could reference a freed pointer.
Only reset queue_io in pg_init_complete if another pg_init isn't required.
Skip process_queued_ios if the queue is empty so that we only trigger a
pg_init if there's I/O.
