can: gs_usb: fix return value of the "set_bittiming" callback

commit d5b42e6607661b198d8b26a0c30969605b1bf5c7 upstream.

The "set_bittiming" callback treats a positive return value as error!
For that reason "can_changelink()" will quit silently after setting
the bittiming values without processing ctrlmode, restart-ms, etc.
