drm: don't associate _DRM_DRIVER maps with a master
A driver will use the _DRM_DRIVER map flag to indicate that it wants to be responsible for removing the map itself, bypassing the DRM's automagic cleanup code. Since the multi-master changes this has been broken, resulting in some drivers having their registers unmapped before it's finished with them.
