[libvirt] [RFC PATCH 07/10] qemu: agent: fix monitor close during first sync

[John Ferlan]

From: Nikolay Shirokovskiy <nshirokovskiy at virtuozzo.com>

Normally if first agent sync is failed we retry. First sync
can also be failed due to agent was closed. In this case we should
fail sync otherwise second attempt will hang.
