[PATCH] Fix debug output in auth.c

The attached patch fixes a parameter juxtaposition and a couple broken RDEBUG statements in auth.c that were trying to print vp_strvalue of a VALUE_PAIR of type integer. I haven't looked but there could very well be other instances of this over in the accounting area, and the Session-Type in auth.c may also need a similar fix. I don't use those codepaths.
