qemu: match alias when looking for proper <interface> to detach.

Browse Source 
Previously we only checked MAC address and PCI address (or CCW

isn't provided and multiple interfaces have the same MAC address (for
example, a virtio + hostdev "teaming" pair - their MAC addresses are
always the same).
