drm/i915/execbuffer: Clear domains before beginning reloc processing
After reordering the sequence of relocating objects, commit 6fe4f1404,
we can no longer rely on seeing all reloc targets prior to performing
the relocation. As a result we were ignoring the need to flush objects
from the render cache and invalidate the sampler caches, resulting in
rendering glitches. So we need to clear the relocation domains earlier.
