Subject[PATCH 3.16 54/72] can: gs_usb: gs_can_open(): prevent memory leak
3.16.79-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Navid Emamdoost <navid.emamdoost@gmail.com>

commit fb5be6a7b4863ecc44963bb80ca614584b6c7817 upstream.

In gs_can_open() if usb_submit_urb() fails the allocated urb should be
released.

Fixes: d08e973a77d1 ("can: gs_usb: Added support for the GS_USB CAN devices")
