j1939: Follow updates of the kernel
This commit patch j1939 feature after the update of the kernel from linux-can-next to mainline. Now promisc option removes filter of the bind. The option is now a parameter in the event_filter. The feature recv_own isn't available, you can't receive on the same socket an emit frame from you. Not a big problem because receive and send method use two different sockets in the implementation.
