Tony Lu 1a74e99323 net/smc: Fix sock leak when release after smc_shutdown() ...

Since commit e5d5aadcf3 ("net/smc: fix sk_refcnt underflow on linkdown
and fallback"), for a fallback connection, __smc_release() does not call
sock_put() if its state is already SMC_CLOSED.

When calling smc_shutdown() after falling back, its state is set to
SMC_CLOSED but does not call sock_put(), so this patch calls it.
