Use accessor (virDomainDefGetVCpusMax)

FWIW: Just thinking about patch 12 where the code is reading off the
command line and setting counts, but not checking that vcpus <= maxvcpus
in qemuParseCommandLineSmp... Although I suspect that won't be a problem
since that code is reading qemu command line and I would hope we could
assume (haha) that qemu would have failed if vcpus > maxvcpus and of
course if cores/threads/sockets didn't add up properly as well.

ACK with the accessor change.
