[libvirt] [PATCH] Allow address lease query with inactive domain

[Amador Pahim]

The <drive>DomainInterfaceAddresses, when using the source type
LEASE, does not need the domain to be running. It only checks the
dhcp lease file and gets the address information from a valid lease,
if any.

This patch removes the virDomainObjIsActive(vm) check from the LEASE
query type on both qemu and lxc drivers, keeping it only for query
type AGENT on qemu driver (since lxc does not support AGENT type).
