commit b70a5cc045197aad9c159042621baf3c015f6cc7 upstream.
In commit ea785a1a573b("net/smc: Send directly when TCP_CORK is cleared"), we don't use delayed work to implement cork.
This patch use the same algorithm, removes the delayed work when setting TCP_NODELAY and send directly in setsockopt(). This also makes the TCP_NODELAY the same as TCP.
