net: fix network drivers ndo_start_xmit() return values (part 8)
Fix up USB drivers that return an errno value (result of usb_submit_urb()) to qdisc_restart(), causing qdisc_restart() to print a warning and requeue/ retransmit the skb. - hso: skb is freed: use after free - at76_usb: skb is freed: use after free Compile tested only.
