## Overview

In the Linux kernel, the following vulnerability has been resolved:

nvmet-tcp: check return value of nvmet_tcp_set_queue_sock

The return value of nvmet_tcp_set_queue_sock() is currently ignored in
nvmet_tcp_tls_handshake_done(). If it fails (e.g., due to the socket
not being in TCP_ESTABLISHED state), the socket callbacks will not be
properly set, leading to queue and socket leakage.

Fix this by capturing the return value and calling
nvmet_tcp_schedule_release_queue() on failure to ensure proper cleanup.

## Affected

- `Linux >= 675b453e024154dd547921c6e6d5b58747ba7e0e < cba2ee57fd302727aea7d41e9d9cd0969f5df0fb`
- `Linux >= 675b453e024154dd547921c6e6d5b58747ba7e0e < 22aa70f9a0544643ec37d442b6fcb1833d804462`
- `Linux >= 675b453e024154dd547921c6e6d5b58747ba7e0e < 7ef789703e2b91775dcb36b2efa46325be31a2a0`
- `Linux 6.7`
