Historically, the GTT pagefault invoked set-domain(GTT) to transparently handle swapin. However, this implied that the GTT faults were synchronous with GPU rendering, which was not the desired ABI, as synchronisation is explicit via calls to GEM_WAIT or GEM_SET_DOMAIN. In MMAP_GTT_VERSION, this accidental ABI is removed and so we test it is gone and does not come back. For completeness, we verify that the other mmap paths didn't block on initial pagefaulting.
