virhostcpu: Fix non-Linux virHostCPUGetPhysAddrSize() stub

The non-Linux version of virHostCPUGetPhysAddrSize() is lacking
G_GNUC_UNUSED attribute to its @size argument which triggers an
error on all non-Linux builds. And while at it, make the function
actually signal error (ENOSYS) since it does not set the
argument.
