Subject[PATCH net 7/7] mptcp: avoid setting TCP_CLOSE state twice
tcp_set_state() is called from tcp_done() already.

There is then no need to first set the state to TCP_CLOSE, then call
tcp_done().

Fixes: d582484726c4 ("mptcp: fix fallback for MP_JOIN subflows")
Cc: stable@vger.kernel.org
Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/362
