[v5,1/6] memory: rename global_dirty_log to global_dirty_tracking

From: Hyman Huang(黄勇) <[e-mail]>

since dirty ring has been introduced, there are two methods
to track dirty pages of vm. it seems that "logging" has
a hint on the method, so rename the global_dirty_log to
global_dirty_tracking would make description more accurate.
