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.
