ublk server pid(the `tgid` of the process opening the ublk device) is stored
in `ublk_device->ublksrv_tgid`. This `tgid` is then checked against the
`ublksrv_pid` in `ublk_ctrl_start_dev` and `ublk_ctrl_end_recovery`.

When restoring the default socket callbacks during a TLS handshake, we
need to acquire a write lock on sk_callback_lock. Previously, a read
lock was used, which is insufficient for modifying sk_user_data and
sk_data_ready.
