randr: Fix RRCrtcDetachScanoutPixmap() segfault during server teardown 



During server teardown, mrootdraw is NULL, which can cause segfaults if
master->Stop{,Flipping}PixmapTracking() don't do NULL checking. In this case we
shouldn't need to do master->Stop{,Flipping}PixmapTracking() anyway, so just
skip it.
