Thanks!  One correction to my commit message, if you're still able to
edit it: the out-of-bounds reads from all three fuzzer reproducers are
on de->flags, not in isonum_733(de->size).  The last paragraph would
then read:

  Found by fuzzing fs/isofs in a userspace harness with ASan
  (heap-buffer-overflow reads of de->flags).
