[MINOR] http-auth: last fix was wrong

I'm not sure if the fix is correct:

- if (req_acl->cond)
-         ret = acl_exec_cond(req_acl->cond, px, s, txn, ACL_DIR_REQ);
+ if (!req_acl->cond)
+         continue;

Doesn't it ignore rules with no condition attached? I think that the
proper solution would be the following.
