rbd-mirror: reset update_status_task pointer in timer thread

To avoid a time window when m_update_status_task is invalid. If
during this time the cancel_update_mirror_image_replay_status is
called, it may cancel some other's ImageReplayer task, if it
happened to add the task with the same address.
