drm/i915: Use i915_gem_object_ggtt_pin_ww for reloc_iomapdrm-intel-fixes-2022-05-20
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.")
