[PATCH] qemu: Fix parsing of x86 CPU models

[Jiri Denemark <jdenemar@xxxxxxxxxx>]

QEMU changed the output of -cpu ? and CPU models can now be followed by
its description. Our parser just used both model name and its
description as a model name, which made any model with a description
unusable with libvirt.
