ACK.  The only other caller of qemudDomainSaveFlag is
qemuDomainManagedSave, and it also checks that vm is active before
calling the helper.

One nit: can you adjust the comment before qemudDomainSaveFlag to
document that vm must be active (it already documents that it is a
helper to be run while the lock is held).

Worth applying before 0.8.8.
