====================
net/smc: fixes 2018-08-08

here are small fixes for SMC: The first patch makes sure, shutdown code
is not executed for sockets in state SMC_LISTEN. The second patch resets
send and receive buffer values for accepted sockets, since TCP buffer size
optimizations for the internal CLC socket should not be forwarded to the
outer SMC socket. The third patch solves a race between connect and ioctl
reported by syzbot.
