D. Wythe c5bf605ba4 net/smc: allow cdc msg send rather than drop it with NULL sndbuf_desc ...

This patch re-fix the issues mentioned by commit 22a825c541
("net/smc: fix NULL sndbuf_desc in smc_cdc_tx_handler()").

Blocking sending message do solve the issues though, but it also
prevents the peer to receive the final message. Besides, in logic,
whether the sndbuf_desc is NULL or not have no impact on the processing
of cdc message sending.

Hence that, this patch allows the cdc message sending but to check the
sndbuf_desc with care in smc_cdc_tx_handler().
