can: rx-offload: can_rx_offload_add_manual(): add new initialization function
This patch adds a new initialization function:
can_rx_offload_add_manual()
It should be used to add support rx-offload to a driver, if the callback
mechanism should not be used. Use e.g. can_rx_offload_queue_sorted() to queue
skbs into rx-offload.
