From: Colin Ian King <colin.king@canonical.com>

The error return path when create_singlethread_workqueue fails currently
does not kfree tls and leads to a memory leak. Fix this by kfree'ing
tls before returning -ENOMEM.

Addresses-Coverity: ("Resource leak")
Fixes: 1182f3659357 ("net/mlx5e: kTLS, Add kTLS RX HW offload support")
