Description

sys/socket.h: Fix AF_MAX

AF_MAX was always intended to be one more than the greatest allocated
value. Jeff broke this in 2013. Unfortunately, a bunch of people then
decided to adapt to the mistake instead of correcting it.

Fixes: 863c7e45628d (" - Reserve a special AF for SDP. The one we were incorrectly using before was taken by another AF.")
