[RFA][PATCH 2/4] tracing: Fix event header migrate.h to include tracepoint.h

[ Request for Ack ]

From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>

The trace event headers are required to include tracepoint.h. The only reason
they worked now is because module.h included tracepoint.h, and that will soon
change. (And the change will be going to the stable tree as well)

Fixes: 7b2a2d4a18ff "mm: migrate: Add a tracepoint for migrate_pages"
