Ursula Braun ce58a36551 net/smc: do not schedule tx_work in SMC_CLOSED state ...

[ Upstream commit f9cedf1a9b1cdcfb0c52edb391d01771e43994a4 ]

The setsockopts options TCP_NODELAY and TCP_CORK may schedule the
tx worker. Make sure the socket is not yet moved into SMC_CLOSED
state (for instance by a shutdown SHUT_RDWR call).
