Revamp watch code to support retrying watch re-registration: - add rbd_dev->watch_state for more robust errcb handling - store watch cookie separately to avoid dereferencing watch_handle which is set to NULL on unwatch - move re-register code into a delayed work and retry re-registration every second, unless the client is blacklisted Signed-off-by:
