doc: clarify documentation for vcpu order
Make it clear that vcpu order is valid for online vcpus only and state
that it has to be specified for all vcpus or not provided at all.

For hypervisors/platforms that require to insert multiple vcpus at once the order may be be duplicated accross all vcpus that need to be enabled at once. Specifying order is not necessary, vcpus are then added in an arbitrary order. I cannot find why libvirt will ignore this configuration from the document Additional info:
