With support of core scheduling sched_unit_migrate_finish() gained a

In case of migrating a vcpu away from a physical cpu for a short period
of time only this might not be true, so drop the call and let the lazy
state syncing do its job.
Replying here instead of on the patch 3 thread (and I'm sorry
for mixing up function names there): By saying "for a short
period of time only", do you imply without ever getting scheduled
on the new (temporary) CPU? If so, I think I understand this
change now, but then this could do with saying here. If not, I'm
afraid I'm still lost.
I'll change the commit message to:
... for a short period of time only without ever being scheduled on the
selected new cpu ...
