[PATCH] sched/fair: Fix update min_vruntime in dequeue_entity()

[Song Muchun]

The comment and the code around 2nd update_min_vruntime() are
not in agreement. From commit b60205c7c558 ("sched/fair: Fix
min_vruntime tracking"), I think that we want to update min_vruntime
when a task is sleeping/migrating. So, the check is inverted there.
