O-Subject: [PATCH] virtio-serial: Disable flow control for RHEL 5.0 machine type
Bugzilla: 588916

Alex pointed out we'll need to disable flow control for RHEL 5 in
addition to RHEL6.0 machine type.
We need to do this to ensure a RHEL6.1+ qemu started with -M rhel5 can
migrate fine to qemu started on a RHEL5.
Bugzilla: 588916
(riding on top of the flow control bug)
