qemu: Assign device addresses earlier in qemuDomainAttachNetDevice

Browse Source 
If code in the @actualType switch needs to have/know which PCI
Address is being used, then we must assign it earlier. In particular
a vhost-user device needs to call qemuDomainSupportsNicdev which
requires an address to be defined.
