[PATCH 3/6] rbd: kill __rbd_remove()

[Alex Elder <elder@inktank.com>]

The function __rbd_remove() is used in two spots, and it's fairly
simple.  It combines cleanup of part of the ceph-side state as well
as cleaning up the Linux-side state.  Just open code it in the two
callers and eliminate the function.
