net: fix race condition in get_ip_from_vm_or_virt_handler_pod

The function read vm.vmi.interfaces[0]["ipAddresses"] once without
waiting. With Fedora 43 the guest agent reports IPs slower than
Fedora 41, so ipAddresses is still None right after AgentConnected
becomes True, causing TypeError on iteration.

Delegate the VM branch to lookup_iface_status_ip which polls the VMI
with a watcher until IPs are reported.
