One line per enum value, please.

I can't believe we don't have a virString helper for this. Oh well.

You're no longer calling virReportError() when the user attempts to
use an unknown transport. While I don't think hardcoding the list of
valid transport in the error message is a good idea, neither is
failing without telling the user what they did wrong. Please restore
the virReportError() call.

Idea for a follow-up patch: "transport" could be cast to
remoteDriverTransport here, so that the compiler will ensure we're
covering all possible values.
Anyway, with the VIR_ENUM_IMPL() arguments formatted correctly and
some error message reported on unknown transport,
