net/smc: fix TCP fallback socket release
[ Upstream commit 78abe3d0dfad196959b1246003366e2610775ea6 ]
clcsock can be released while kernel_accept() references it in TCP
listen worker. Also, clcsock needs to wake up before released if TCP
fallback is used and the clcsock is blocked by accept. Add a lock to
safely release clcsock and call kernel_sock_shutdown() to wake up
clcsock from accept in smc_release().
