kms_frontbuffer_tracking: properly handle mixing GTT and WC mmaps
The new Kernel behavior is that whenever a buffer has ever been WC
mmapped, the GTT mmaps will be treated as CPU operations. Because of
this, if we don't issue the dirty_fb IOCTL after doing frontbuffer
rendering with the GTT mmaps, FBC will remain disabled. Luckily, the
only subtest that does this sort of mix is the multidraw subtest.
