qemu: save domain status after set domain's numa parameters

After set domain's numa parameters for running domain, save the change,
save the change into live xml is needed to survive restarting the libvirtd,
same story with bug 1146511; meanwihle add call
qemuDomainObjBeginJob/qemuDomainObjEndJob in qemuDomainSetNumaParameters
