md/raid5: remove setting of ->queue_lock
We previously needed to set ->queue_lock to match the raid5 device_lock so we could safely use queue_flag_* operations (e.g. for plugging). which test the ->queue_lock is in fact locked. However that need has completely gone away and is unlikely to come back to remove this now-pointless setting. Signed-off-by: NeilBrown <neilb@suse.de>
