[Qemu-devel] [PATCH 3/3] Handle parse failures in CPU definitions, and avoid adding a partial cpudef

[Josh Triplett <josh@joshtriplett.org>]

Without this change, a parse failure would stop the processing of the
cpudef entry, but the partially-parsed CPU definition would still get
added to the list of CPUs.
