kernel - Fix improper persist state in tcp

* When TCP is doing a simultanious connect and sitting in the
  TCPS_SYN_RECEIVED state a degenerate 0 window (due to +SYN -ACK packets)
  case occurs where the code improperly tries to switch over from the
  retry timer to the persist timer, which panics.

  The invalid persist state was caught by code placed earlier in the
  year.

* Adjust the code to document the case and stay with the retry timer.
