From: Ridong Chen <redacted>

memcontrol.c includes <trace/events/vmscan.h> but does not use any of
the tracepoints or macros it defines: all tracepoints invoked here come
from memcg.h and writeback.h.

Drop it ahead of moving the vmscan trace header under mm/, after which
<trace/events/vmscan.h> will no longer exist.

No functional change.
