Having the whole device name in one string would be nicer than dealing
with the device suffix, e.g.:
if (type == _CCW)
device = "vhost-vsock-ccw"
else
device = "vhost-vsock-pci"
(or even virBufferAddLit, without the temporary variable - I forgot what
led me to use it)

This whole comment is pointless - it's repeating what the function does,
not why.

It would be nice to extend the LATEST caps coverage to s390 as well, to
make sure that adding a new capability won't affect the vsock device.
