Please address the user-visible behavior in your commit messages.
Does it crash? Does it send frames to an invalid peer? Do
frames get dropped?

"PREQ"
Please split this into a separate patch that we can review

This isn't necessary, caller should already be doing
mesh_path_flush_by_nexthop() in every case I could see. Besides it
