Subject: [PATCH] lavc/qsvenc: fix poor video quality with "-force_key_frames"
if run ffmpeg with "-force_key_frames" flag without this fix,
all new frames will have "MFX_FRAMETYPE_I | MFX_FRAMETYPE_REF"
after some time and video quality will become very poor.
Need to reset FrameType in free_encoder_ctrl_payloads.
