rbd: set up watch before announcing disk
We're ready to handle header object (refresh) events at the point we call rbd_bus_add_dev(). Set up the watch request on the rbd image header just after that, and after we've registered the devices for the snapshots for the initial snapshot context. Do this before announce the disk as available for use. Signed-off-by: Alex Elder <elder@inktank.com> Reviewed-by: Josh Durgin <josh.durgin@inktank.com>
