BUG/MINOR: auth: fix wrong return type in pat_match_auth()

Commit 5338eea ("MEDIUM: pattern: The match function browse itself the
list or the tree") changed the return type of pattern matching functions.
One enum was left over in pat_match_auth(). Fortunately, this one equals
zero where a null pointer is expected, so it's cast correctly.

This detected and reported by Charles Carter was introduced in 1.5-dev23,
no backport is needed.
