Marc Kleine-Budde 95c5637d3d can: gs_usb: gs_can_open(): fix race dev->can.state condition 
[ Upstream commit 5440428b3da65408dba0241985acb7a05258b85e ]

The dev->can.state is set to CAN_STATE_ERROR_ACTIVE, after the device
has been started. On busy networks the CAN controller might receive
CAN frame between and go into an error state before the dev->can.state
is assigned.

Assign dev->can.state before starting the controller to close the race
window.

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