[PATCH v4 3/7] net/handshake: Ensure the request is destructed on completion

[alistair23 at gmail.com]

From: Alistair Francis <alistair.francis at wdc.com>

To avoid future handshake_req_hash_add() calls failing with EEXIST when
performing a KeyUpdate let's make sure the old request is destructed
as part of the completion.

Until now a handshake would only be destroyed on a failure or when a
sock is freed (via the sk_destruct function pointer).
handshake_complete() is only called on errors, not a successful
handshake so it doesn't remove the request.
