A bug can be easily reproduced:
Host# cat guest-agent.xml
Host# virsh attach-device instance guest-agent.xml
Host# virsh detach-device instance guest-agent.xml
Host# virsh attach-device instance guest-agent.xml
and guest report: virtio-ports vport0p1: Error allocating inbufs
The reason
There are lots of mismatches between comments and codes, this
patch do these comment fixes.
