Subject: [PATCH] logind: simplify flags handling a bit
Let's split out the two codepaths a bit, and emphasize which ones it the
new-style and which the old-style codepath, and let's clearly convert
the params of the old-stye into the new style for further processing, so
that the old style path is brief and isolated.
No change in behaviour.
