can: gs_usb: gs_can_open(): fix race dev->can.state condition
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")
