This patch disables detect_vsmp_box() on systems without CONFIG_X86_VSMP, due to
the recent 6da63eb241a05b0e676d68975e793c0521387141.  This is significant
regression that will affect significant number of deployments.

We will reply shortly with an updated patch that fix the dependency on pv_irq_ops,
and revert to CONFIG_PARAVIRT, with proper protection for CONFIG_PCI.
