Subject: [PATCH v2] netlabel: remove unused param from audit_log_format()

Commit d3b990b7f327 ("netlabel: fix problems with mapping removal")
added a check to return an error if ret_val != 0, before ret_val is
later used in a log message. Now it will unconditionally print "...
res=1". So just drop the check.

Addresses-Coverity: ("Dead code")
Fixes: d3b990b7f327 ("netlabel: fix problems with mapping removal")

v2: Still print the res field, because it's useful (Paul)
