Seems reasonable since the reproducer here manages to modify ENDPOINT0
attrs and this leads to the invalid behaviour in different ways - the one
is this bug and another is the one fixed by the commit which syzbot
bisected. Those attempts to modify ENDPOINT0 are now prohibited with this
commit. So I think the result is correct (apart from that this issue is
not related to afs).
#syz fix: wifi: ath9k: don't allow to overwrite ENDPOINT0 attributes
