can: kvaser_usb_leaf: Fix bogus restart events
When auto-restart is enabled, the kvaser_usb_leaf driver considers
transition from any state >= CAN_STATE_BUS_OFF as a bus-off recovery
event (restart).
However, these events may occur at interface startup time before
kvaser_usb_open() has set the state to CAN_STATE_ERROR_ACTIVE, causing
restarts counter to increase and CAN_ERR_RESTARTED to be sent despite no
actual restart having occurred.
Fix that by making the auto-restart condition checks more strict so that
they only trigger when the interface was actually in the BUS_OFF state.
Fixes: 080f40a6fa28 ("can: kvaser_usb: Add support for Kvaser CAN/USB devices")
