fix affs parse_options()
commit 217686e98321a4ff4c1a6cc535e511e37c5d2dbf upstream. Error handling in that sucker got broken back in 2003. If function returns 0 on failure, it's not nice to add return -EINVAL into it. Adding return 1 on other failure exits is also not a good thing (and yes, original success exits with 1 and some of failure exits with 0 are still there; so's the original logics in callers).
