drm/xe: Adjust page count tracepoints in shrinker
Page accounting can change via the shrinker without calling
xe_ttm_tt_unpopulate(), which normally updates page count tracepoints
through update_global_total_pages. Add a call to
update_global_total_pages when the shrinker successfully shrinks a BO.
v2:
- Don't adjust global accounting when pinning (Stuart)
