[Qemu-devel] [PATCH] vl.c: Check max_cpus limit instead of smp_cpus |

If a given machine have max_cpus set, not just smp_cpus needs to be
limited, but the total number of CPUs (considering CPU hotplug) for the
machine.
As smp_parse() already ensures smp_cpus <= max_cpus, we just need to
check if max_cpus exceeds the limit.
