qemu: assign USB port on a selected hub for all devices
Due to a logic error, the autofilling of USB port when a bus is
specified:
<address type='usb' bus='0'/>
does not work for non-hub devices on domain startup.
Fix the logic in qemuDomainAssignUSBPortsIterator to also
assign ports for USB addresses that do not yet have one.

1. Define a vm with following xml

## virsh define vm1.xml
Domain vm defined from vm1.xml
2. prepare a qcow2 image and use it in the vm
## qemu-img create -f qcow2 /tmp/1.qcow2 1G
Formatting '/tmp/1.qcow2', fmt=qcow2 size=1073741824 encryption=off cluster_size=65536 lazy_refcounts=off refcount_bits=16

...
## virsh start vm
Domain vm started
