This doesn't operate on the device, but on the resource_manager. It's
just stuck using the old api of (bdev, man_type) pairs instead of the
pointer. I think switching to the pointer, renaming it to
ttm_resource_manager_evict and moving it to ttm_resource.[hc] is a lot
cleaner. Or did I again get confused somewhere :-)
