md/plug: optionally use plugger to unplug an array during resync/recovery.
If an array doesn't have a 'queue' then md_do_sync cannot unplug it. In that case it will have a 'plugger', so make that available to the mddev, and use it to unplug the array if needed. Signed-off-by: NeilBrown <neilb@suse.de>
