commit 3e54d3b4a8 upstream.
Commit 2603be9e81 ("can: gs_usb: gs_can_open(): improve error handling")
added missing error handling to the gs_can_open() function.
The driver uses 2 USB anchors to track the allocated URBs: the TX URBs in
struct gs_can::tx_submitted for each netdev and the RX URBs in struct
gs_usb::rx_submitted for the USB device. gs_can_open() allocates the RX
URBs, while TX URBs are allocated during gs_can_start_xmit().
The cleanup in gs_can_open() kills all anchored dev->tx_submitted
URBs (which is not necessary since the netdev is not yet registered), but
misses the parent->rx_submitted URBs.
Fix the problem by killing the rx_submitted instead of the tx_submitted.
