  TCP engine: Fix incorrect returned bytes on async writes

This isn't actually as bad of a bug as it would seem. By occasionally
reporting _less_ written bytes than normal, the TCP write flow may trigger
some false async write requests to TCP MAIN. The connection will
eventually end up in a writer which simply sends it back, as it does not
contain any chunks which require writing.
