rbd: retry watch re-registration periodically
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
