rbd: get rid of rbd_req_sync_exec()
Get rid rbd_req_sync_exec() because it is no longer used. That eliminates the last use of rbd_req_sync_op(), so get rid of that too. And finally, that leaves rbd_do_request() unreferenced, so get rid of that. Signed-off-by: Alex Elder <elder@inktank.com> Reviewed-by: Josh Durgin <josh.durgin@inktank.com>
