[libvirt] [PATCH] vz: fixup: do not touch domain cache on error path on migration finish step

[Nikolay Shirokovskiy]

 We can not and should not sync domain cache on error path in finish step
of migration. We can not as we really don't know what is the reason of
cancelling and we should not as user should not make assumptions on
state on error path. What we should do is cleaning up temporary migration
state that is induced on prepare step but we don't have one. Thus
cancellation should be noop.

 So, please, fixup 5th patch of series and this patch into 4th one.
