md: md_stop_writes requires mddev_lock. As md_stop_writes manipulates the sync_thread and calls md_update_sb, it need to be called with mddev_lock held. In all internal cases it is, but the symbol is exported for dm-raid to call and in that case the lock won't be help. Do make an exported version which takes the lock, and an internal version which does not. Signed-off-by: NeilBrown <neilb@suse.de>
