[Impact] Remove the redundant updating of stats_flush_threshold. If the global var stats_flush_threshold has exceeded the trigger value for __mem_cgroup_flush_stats, further increment is unnecessary. This is targeting Sapphire Rapids platforms. [Fix] Upstream commit 873f64b791a2 fixes this issue. The fix involves not updating the status after a certain threshold has been hit as it is unnecessary. [Test Plan] I have tested the changes, and hit no regressions. [Where problems could occur] As the change has been upstream since 6.0-rc1, and is reducing a stats update which isn't needed, the change for regressions should be minimal.
