udplite: Print deprecation notice.
Recently syzkaller reported a 7-year-old null-ptr-deref [0] that occurs
when a UDP-Lite socket tries to allocate a buffer under memory pressure.
Someone should have stumbled on the bug much earlier if UDP-Lite had been
used in a real app. Also, we do not always need a large UDP-Lite workload
to hit the bug since UDP and UDP-Lite share the same memory accounting
limit.
Removing UDP-Lite would simplify UDP code removing a bunch of conditionals
in fast path.
Let's add a deprecation notice when UDP-Lite socket is created and schedule
its removal to 2025.
