Chris Wilson a415d35564 drm/i915: Pin relocations for the duration of constructing the execbuffer 
As the execbuffer dispatch grows ever more complex and involves multiple
stages of moving objects into the aperture, we need to take greater care
that we do not evict our execbuffer objects prior to dispatch. This is
relatively simple as we can just keep the objects pinned for not just
the relocation but until we are finished.

One such example is the possibility of the context switch causing an
eviction or hitting the shrinker in order to fit its object into the
aperture.
