ipv[4|6]: correct dropwatch false positive in local_deliver_finish
I had a report recently of a user trying to use dropwatch to localise some frame
loss, and they were getting false positives. Turned out they were using a user
space SCTP stack that used raw sockets to grab frames. When we don't have a
registered protocol for a given packet, we record it as a drop, even if a raw
socket receieves the frame. We should only record the drop in the event a raw
socket doesnt exist to receive the frames
