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 can_rx_offload_receive_skb() (added in
the next patch) to queue skbs into rx-offload.
