[video_player_avplay] Call the open before calling the SetStreamingProperty

[xiaowei-guan]

From SetStreamingProperty API guide:

  /**
   * @brief     Set streamingengine property
   * @param     [in] type : attribute type. \n
   *             type can be \n
   *               "COOKIE" \n
   *               "USER_AGENT" \n
   *               "RESUME_TIME" \n
   *               "ADAPTIVE_INFO"
   * @param     [in] value : value of attribute type
   * @pre       The player state can be all of #State except #State::kNone
   */

We need call open first, then call SetStreamingProperty.
