ceph: re-send AIO write request when getting -EOLDSNAP error
When receiving -EOLDSNAP from OSD, we need to re-send corresponding write request. Due to locking issue, we can send new request inside another OSD request's complete callback. So we use worker to re-send request for AIO write. Signed-off-by: Yan, Zheng <zyan@redhat.com>
