[PATCH v4 2/7] net/handshake: Define handshake_sk_destruct_req

[alistair23 at gmail.com]

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

Define a `handshake_sk_destruct_req()` function to allow the destruction
of the handshake req.

This is required to avoid hash conflicts when handshake_req_hash_add()
is called as part of submitting the KeyUpdate request.
