qemu: security patch for CVE-2014-3471

Qemu PCIe bus support is vulnerable to a use-after-free flaw. It could
occur via guest, when it tries to hotplug/hotunplug devices on the
guest.

A user able to add & delete Virtio block devices on a guest could use
this flaw to crash the Qemu instance resulting in DoS.
