Chris Wilson df6f783a4e drm/i915: Fix unsafe loop iteration over vma whilst unbinding them 
On non-LLC platforms, when changing the cache level of an object, we may
need to unbind it so that prefetching across page boundaries does not
cross into a different memory domain. This requires us to unbind
conflicting vma, but we did so iterating over the objects vma in an
unsafe manner (as the list was being modified as we iterated).

The regression was introduced in
commit 3089c6f239

    drm/i915: make caching operate on all address spaces
apparently as far back as v3.12-rc1, but it has only just begun to
trigger real world bug reports.
