kvm/powerpc/e500mc: fix tlb invalidation on cpu migration
commit c5e6cb051c5f7d56f05bd6a4af22cb300a4ced79 upstream.
The existing check handles the case where we've migrated to a different
core than we last ran on, but it doesn't handle the case where we're
still on the same cpu we last ran on, but some other vcpu has run on
this cpu in the meantime.
Without this, guest segfaults (and other misbehavior) have been seen in
smp guests.
