[PATCH 3/6]NET:AX25:ROSE Traps calls to rose_route_frame with a NULL ax25 callback

Hi Richard,

Thanks for this patch and all others for ROSE code you sent recently.
I already committed a similar one in february 2016.

You may browse linux servers for author f6bvp and see my last findings about null ax25.

However, despite all my efforts, I did no convince referees of the patch's legitimity and it had not been accepted.
I hope your work for improving rose code will be successful to the benefit of all radioamateur packet community!
