Make sure bogus values don't make their way into tcp_xmit_timer() calculations.

- Ignore ts_ecr if it is 0, or the resulting rtt is out of range.
  (use tp->t_rtttime instead)
- Initialise tcp_now to 1, to avoid the 500ms window where a valid ts_ecr
  of 0 could be ignored.
- Convert out-of-range rtt values to valid ones in tcp_xmit_timer().
