nvmet-tcp: fixup hang in nvmet_tcp_listen_data_ready()
[ Upstream commit 2fa8961d3a6a1c2395d8d560ffed2c782681bade ]
When the socket is closed while in TCP_LISTEN a callback is run to
flush all outstanding packets, which in turns calls
nvmet_tcp_listen_data_ready() with the sk_callback_lock held.
So we need to check if we are in TCP_LISTEN before attempting
to get the sk_callback_lock() to avoid a deadlock.
