[libvirt] [PATCH v2 3/5] virDomainFormatSchedDef: factor out subset code

The code within the function is too specific for priority attribute of RT schedulers. To allow addition of schedulers that group by different properties, we factor out the logic to calculate cpu subset. Instead of comparing by priority, the new code accepts comparator for the 2 sched structs. ---
