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.
