ath9k: Fix potential out of bounds in ath9k_htc_txcompletion_cb()
The value of "htc_hdr->endpoint_id" comes from skb->data so Smatch marks
it as untrusted so we have to check it before using it as an array
offset.
This is similar to a bug that syzkaller found in commit e4ff08a4d727
("ath9k: Fix use-after-free Write in ath9k_htc_rx_msg") so it is
probably a real issue.
Fixes: fb9987d0f748 ("ath9k_htc: Support for AR9271 chipset.")
