Restrict enabling TCP-FASTOPEN to end-points in CLOSED or LISTEN state

Enabling TCP-FASTOPEN on an end-point which is in a state other than
CLOSED or LISTEN, is a bug in the application. So it should not work.
Also the TCP code does not (and needs not to) handle this.
While there, also simplify the setting of the TF_FASTOPEN flag.
