The commit 03fb92a432ea ("ath9k: hif_usb: fix race condition between
usb_get_urb() and usb_kill_anchored_urbs()") adds three usb_get_urb
in ath9k_hif_usb_dealloc_tx_urbs and usb_free_urb.
Fix this bug by adding corresponding usb_free_urb in
ath9k_hif_usb_dealloc_tx_urbs other and hif_usb_stop.

Signed-off-by: Dongliang Mu <redacted>In the past there have been so many problems with ath9k syzbot fixes that I have now a hard time trusting them. Can someone review this in detail, please? -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
