drm/i915: Request PIN_GLOBAL when pinning a vma for GTT relocations
Always require PIN_GLOBAL when we want a mappable offset (PIN_MAPPABLE). This causes the pin to fixup the global binding in cases were the vma was already bound (and due to the proceeding bug, we considered it to be already mappable).
