[libvirt] [PATCH] qemu_agent: report VIR_ERR_AGENT_UNSYNCED if guest_sync failed.

[Chen Hanxiao]

From: Chen Hanxiao <chenhanxiao at gmail.com>

Commit 5e5019bf removed this kind of error.

But we've already protected race condition by qemuDomainObjEnterAgent,
it was very unlikely to revieve a sync from other calls.
For call from virDomain*, it's better to show this error
if we really got a mismatch sync.
