sched: Fix migrate_disable_switch() locking
For some reason migrate_disable_switch() was more complicated than it
needs to be, resulting in mind bending locking of dubious quality.
Recognise that migrate_disable_switch() must be called before a
context switch, but any place before that switch is equally good.
Since the current place results in troubled locking, simply move the
thing before taking rq->lock.
