can: kvaser_usb_leaf: Fix CAN state after restart

commit 0be1a655fe68c8e6dcadbcbddb69cf2fb29881f5 upstream.

can_restart() expects CMD_START_CHIP to set the error state to
ERROR_ACTIVE as it calls netif_carrier_on() immediately afterwards.

Otherwise the user may immediately trigger restart again and hit a
BUG_ON() in can_restart().

Fix kvaser_usb_leaf set_mode(CMD_START_CHIP) to set the expected state.
