The --probe-maxsmp parameter updates MAX_SMP with the maximum number of
VCPUs that the host supports. Qemu will exit with an error when creating a
virtual machine if the number of VCPUs is exceeded.

kvmtool behaves differently: it will automatically limit the number of
VCPUs to the what KVM supports, which is exactly what --probe-maxsmp wants
to achieve. When doing --probe-maxsmp with kvmtool, print a message
explaining why it's redundant and don't do anything else.
