Guvenc Gulce 17081633e2 net/smc: Ensure correct state of the socket in send path 
When smc_sendmsg() is called before the SMC socket initialization has
completed, smc_tx_sendmsg() will access un-initialized fields of the
SMC socket which results in a null-pointer dereference.
Fix this by checking the socket state first in smc_tx_sendmsg().

Fixes: e0e4b8fa53 ("net/smc: Add SMC statistics support")
