net: permit WriteMsgUDP to connected UDP sockets

The sanity checks at the beginning of WriteMsgUDP were too
strict, and did not allow a case sendmsg(2) suppports: sending
to a connected UDP socket.

This fixes the sanity checks. Either the socket is unconnected,
and a destination addresses is required (what all existing callers
must have been doing), or the socket is connected and an explicit
destination address must not be used.

Fixes #9807
