Usually on domain shutdown event comes first from qemu
and the flag is unset in processSerialChangedEvent. However
there is a race between this function and qemuProcessHandleAgentEOF
because the former is executed in a thread pool and the latter
executed synchronously. qemuProcessHandleAgentEOF do not unset
the flag thus if it was triggered before it remains set after domain
shutdown/start and thus qemu agent becomes unavailable.
