drm/xe: Skip clearing purged page-table BOs
VRAM page offlining can clear a page-table BO's vmap before VM teardown
calls xe_pt_clear(). Check for a purged BO under its dma-resv lock before
writing to the mapping.
v4(Sashiko):
- dont leave svm notifier lock early
v3(Sashiko):
- Validate NULL vmap
v2(Sashiko):
- Fix lock ordering
