The patchset fix the issue caused by the following modifications:
commit 04e906839a053f092ef53f4fb2d610983412b904
(usbnet: fix cyclical race on disconnect with work queue)

The issue:
The usb_submit_urb function lacks a usbnet_going_away validation,
whereas __usbnet_queue_skb includes this check. This inconsistency
creates a race condition where: A URB request may succeed, but
the corresponding SKB data fails to be queued.

Subsequent processes (e.g., rx_complete → defer_bh → __skb_unlink(skb, list))
attempt to access skb->next, triggering a NULL pointer dereference (Kernel Panic).

Fix issue:
adding the usbnet_going_away check in usb_submit_urb to synchronize the validation logic.
