drm/i915: Use i915_gem_object_ggtt_pin_ww for reloc_iomap
When removing short term pins, I've changed the the batch buffer
pinning for relocation to use __i915_vma_pin, because
i915_gem_object_ggtt_pin_ww was destroying the old vma. This
caused regressions, because the functions are not identical.
Fix the regressions by calling i915_gem_object_ggtt_pin_ww() again
on ggtt-only platforms, but only if the batch can be pinned without
being moved.
Fixes: b5cfe6f7a6e1 ("drm/i915: Remove short-term pins from execbuf, v6.")
