md-cluster: don't send msg if array is closing
If we close an array which resync thread is running, then we don't need the node to send msg since another node would launch the resync thread to continue the rest works. Also send a message is time consuming, we should avoid it. Signed-off-by: Guoqing Jiang <gqjiang@suse.com> Reviewed-by: NeilBrown <neilb@suse.com> Signed-off-by: Shaohua Li <shli@fb.com>
