can: gs_usb: gs_can_close(): add missing set of CAN state to CAN_STATE_STOPPED
After an initial link up the CAN device is in ERROR-ACTIVE mode. Due
to a missing CAN_STATE_STOPPED in gs_can_close() it doesn't change to
STOPPED after a link down:
| ip link set dev can0 up
| ip link set dev can0 down
| ip --details link show can0
| 13: can0: <NOARP,ECHO> mtu 16 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 10
| link/can promiscuity 0 allmulti 0 minmtu 0 maxmtu 0
| can state ERROR-ACTIVE restart-ms 1000
Add missing assignment of CAN_STATE_STOPPED in gs_can_close().
