Fix a typo and update the setting in the example. The documentation
explains that "when passt is the backend,...the ``<source>``
path/type/mode are all implied to be "matching the passt process"
so **must not** be specified." Additionally, this source dev setting is
ignored in practice. Therefore, let's remove it from the example to
avoid any
confusion.

Oops, I have not looked at how this renders when reviewing the original
patch - that the extra characters prevent the :since: tag from working.

So the asterisk ending the italics and the ending parenthesis should be

Yeah, sorry I didn't notice that the italicization not only didn't work,
but also prevented the :since: tag from working. That's unfortunate - I
would have preferred for that paragraph to be italicized :-/
I can squash that change in before pushing, unless someone objects
to removing the italics and parenthesis.

It is correct the path/type/mode in <source> are not used or allowed for
type='vhostuser', but that's not what is being set in this example - it
is setting source dev, which *is* valid to set - for both flavors of
passt connection the source dev is the name of the host network device
passt uses when figuring out what default route to provide to the guest
in its DHCP responses (and also what IP address and netmask to provide
by default in the DHCP response when specific IP/netmask aren't set).
So this line should remain in the example. Please don't remove it.
