can/netlink: add CAN_CTRLMODE_ONE_SHOT
This patch adds the flag CAN_CTRLMODE_ONE_SHOT. It is used as mask or flag in the "struct can_ctrlmode". It allows userspace via netlink to set a CAN controller into the special "one-shot" mode. In this mode, if supported by the CAN controller, it tries only once to deliver a CAN frame and aborts it if an error (e.g.: arbitration lost) happens.
