Per device permissive mode is broken in 4.0. I was trying to figure out
where exactly while troubleshooting my Atheros card. I found where the
init script in the stubdomain reads the device values from xenstore, but I
couldn't find anywhere that actually added per device permissive entries
to xenstore (whereas I did find where msitranslate and power_mgmt got
set).

For my troubleshooting, I set the init script to default to
permissive=true which results in every device being added as permissive
but it didn't help my Atheros case anyways.
