Ursula Braun 07cb0b54d7 net/smc: fix shutdown in state SMC_LISTEN 
[ Upstream commit 1255fcb2a655f05e02f3a74675a6d6525f187afd ]

Calling shutdown with SHUT_RD and SHUT_RDWR for a listening SMC socket
crashes, because
   commit 127f49705823 ("net/smc: release clcsock from tcp_listen_worker")
releases the internal clcsock in smc_close_active() and sets smc->clcsock
to NULL.
For SHUT_RD the smc_close_active() call is removed.
For SHUT_RDWR the kernel_sock_shutdown() call is omitted, since the
clcsock is already released.

Fixes: 127f49705823 ("net/smc: release clcsock from tcp_listen_worker")
