sched: Reset sched stats on fork()
sched: Reset sched stats on fork()

The sched_stat fields are currently not reset upon fork.
Ingo's recent commit 6c594c21fcb02c662f11c97be4d7d2b73060a205
did reset nr_migrations, but it didn't reset any of the
others.

This patch resets all sched_stat fields on fork.
