Every other place properly checks whether we've managed to set up the stolen allocator at boot-up properly, with the exception of the cleanup code. Which results in an ugly *ERROR* Memory manager not clean. Delaying takedown at module unload time since the drm_mm isn't initialized at all. v2: While at it check whether the stolen drm_mm is initialized instead of the more obscure stolen_base == 0 check.
