[libvirt] [PATCH] qemu: Remove maximum cpu limit when setting processor count using the API

[Peter Krempa]

When setting processor count for a domain using the API libvirt enforced
a maximum processor count, while it isn't enforced when taking the XML path.

This patch removes the check to match the API.
