> RBF: Optimize multiple mount point removal

> Since each remove operation forces an update on all routers, removing a lot
> of mount points in one go when there are a decent number of routers can take
> a long time. It's better to just remove all of them in a batch and force
> update only once. Useful for nuking old unused mount points.
