wifi: ath9k: don't allow to overwrite ENDPOINT0 attributes
[ Upstream commit 061b0cb9327b80d7a0f63a33e7c3e2a91a71f142 ]
A bad USB device is able to construct a service connection response
message with target endpoint being ENDPOINT0 which is reserved for
HTC_CTRL_RSVD_SVC and should not be modified to be used for any other
services.
Reject such service connection responses.
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
Fixes: fb9987d0f748 ("ath9k_htc: Support for AR9271 chipset.")
