[PATCH] sockets: Remove deadcode

[PATCH] sockets: Remove deadcode

[dave]

From: "Dr. David Alan Gilbert" <dave@treblig.org>

socket_remote_address hasn't been used since it was added in
  17c55decec ("sockets: add helpers for creating SocketAddress from a socket")

inet_connect hasn't been used since 2017's
  8ecc2f9eab ("sheepdog: Use SocketAddress and socket_connect()")

Remove them.

Excellent ! The more of sockets.h we can remove the better.
