subparse: Check the time is valid when calculating the duration

  - In the case of sami subtitles, the duration for the last subtitle data is wrong.
  - The time value used to calculate the duraion is invalid,
    So the calculated duration is also wrong.
  - If the time is GST_CLOCK_TIME_NONE, the duration also be GST_CLOCK_TIME_NONE
