qemu: remove pointless address validation on hot unplug

Back in the times of using 'pci_del', unplugging a device without
a PCI address was not wired up.

After completely removing support for qemu without QEMU_CAPS_DEVICE,
aliases are used to uniquely identify devices in all cases.

Remove the pointless validation of data that was already present
in the domain definition.
