Quick Emulator(Qemu) built with the i8255x (PRO100) NIC emulation support is
vulnerable to a memory leakage issue. It could occur while unplugging the
device, and doing so repeatedly would result in leaking host memory affecting,
other services on the host.

A privileged user inside guest could use this flaw to cause a DoS on the host
and/or potentially crash the Qemu process on the host.

Fix memory leak and simplify code for VMStateDescription

Use CVE-2016-9101.

This is not yet available at
http://git.qemu.org/?p=qemu.git;a=history;f=hw/net/eepro100.c but
that may be an expected place for a later update.
