drm/xe: Adjust page count tracepoints in shrinker

Browse source

commit ca9e5115e8 upstream.

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)
