O-Subject: [RHEL-5 kvm PATCH] New slots need dirty tracking enabled when
	migrating.
Bugzilla: 567046
RH-Acked-by: Alex Williamson <alex.williamson@redhat.com>

When the guest remaps PCI regions kvm will delete and re-create the
memory slots.  When creating the new slots we have to enable dirty
logging there in case migration is in progress, otherwise reading
the dirty maps for the remapped PCI region stops working.

bugzilla: #567046
