[libvirt] [PATCH v2] qemu: Error prompt when saving a shutoff domain

[Osier Yang]

"qemudDomainSaveFlag" goto wrong label "endjob", which will cause
error when security manager trying to restore label (regression).

As it's more reasonable to check if vm is shutoff immediately, and
return right away if it is, remove the checking in "qemudDomainSaveFlag",
and add checking in "qemudDomainSave".
