Since QEMU 2.3, we have a vmdesc section in the migration stream.
This section is not mandatory but when migrating a pseries-2.2
machine from QEMU 2.2, you get a warning at the destination:
qemu-system-ppc64: Expected vmdescription section, but got 0
The warning goes away if we decide to skip vmdesc as well for
older pseries, like it is already done for pc's.
This can only be observed with -cpu POWER7 because POWER8
cannot migrate from QEMU 2.2 to 2.3 (insns_flags2 mismatch).
