Log service princ in KDC more reliably

Under some error conditions, the KDC would log "<unknown server>" for
the service principal because service principal information is not yet
available to the logging functions.  Set the appropriate variables
earlier.

do_as_req.c: After unparsing the client, immediately unparse the
server before searching for the client principal in the KDB.

do_tgs_req.c: Save a pointer to the client-requested service
principal, to make sure it gets logged if an error happens before
search_sprinc() successfully completes.
