idr_destroy() can destroy idr by itself and idr_remove_all() is being
deprecated.  Drop its usage.

* drm_ctxbitmap_cleanup() was calling idr_remove_all() but forgetting
  idr_destroy() thus leaking all buffered free idr_layers.  Replace it
  with idr_destroy().

This patch depends on an earlier idr patch and given the trivial
nature of the patch, I think it would be best to route these together
through -mm.  Please holler if there's any objection.

Thanks.
