Subject: drm/i915: Use i915_gem_object_ggtt_pin_ww for reloc_iomap

Alt-commit: 451374eef622fca6f00eeeda89aaccb45a30a149
Git-commit: 7b1d6924f27ba24b9e47abb9bd53d0bbc430a835
Patch-mainline: v5.18
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
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.
