    i915: Mark up some forgotten set-domain
    
    It is the user's responsibility to manage their domains. In libdrm, when
    you mmap a pointer, it calls set-domain automatically, but igt requires
    the caller to manage it explicitly, so do so. The vast majority already
    do correct manage the domain as they use the pointer into the mmap, just
    a few have been missed over the years.
