when freeing the DRM_SHM kernel memory that can be mapped by a user process,
remove any user mappings before freeing the memory, so that a user process
doesn't have still have access to that physical memory after it's reused.
this really shouldn't be using kernel malloc'd memory at all,
but changing that would be much more involved.
