[libvirt] [PATCH v2 03/10] qemu: remove vioserialaddrs caching

[Tomasz Flendrich]

Dropping the caching of virtio serial address set.
The cached set is not required anymore, because the set is now being
recalculated from the domain definition on demand, so the cache
can be deleted.

Credit goes to Cole Robinson.
