[libvirt] [PATCH 2/4] Add missing device type check in QEMU PCI hotunplug

[Daniel P. Berrange]

The QEMU hotunplug code for PCI devices was looking at host
devices in the guest config without first filtering non
PCI devices. This means it was reading garbage

* src/qemu/qemu_driver.c: Filter out non-PCI devices
