We will ignore --maximum option when only use setvcpus with this option, like this (this error is another issue):
# virsh setvcpus test3 --maximum 10 error: Failed to create controller cpu for group: No such file or directory
this is because we do not set it in flags before we check if there is a flags set.
Refactor these code and fix the logic.
