If the agent is set to daemonize but for whatever reason fails to
init the channel, the error message is lost. Worse, the agent
daemonizes needlessly and returns success. For instance:
# qemu-ga -m virtio-serial \
-p /dev/nonexistent_device \
-f /run/qemu-ga.pid \
-t /run \
-d
# echo $?
0
This makes it needlessly hard for init scripts to detect a
failure in qemu-ga startup. Though, they shouldn't pass '-d' in
the first place.
Let's open the channel first and only after that become a daemon.
