TLS resets the protocol operations, so the read_sock() callback might
be changed, too.
In this case using sock->ops->readsock() in tls_strp_read_copyin() will
enter an infinite recursion if the read_sock() callback is calling
tls_rx_rec_wait() which will call into sock->ops->readsock() via
tls_strp_read_copyin().
But as tls_strp_read_copyin() is supposed to produce data from the
consumed socket and that socket is always a TCP socket we can call
tcp_read_sock() directly without having to deal with callbacks.
