lavc/encode: fix frame_number double-counted
Encoder frame_number may be double-counted if some frames are cached and then flushed. Take qsv encoder (some frames are cached firsty for asynchronism) as example, ./ffmpeg -loglevel verbose -hwaccel qsv -c:v h264_qsv -i in.mp4 -vframes 100 -c:v h264_qsv out.mp4 frame_number passed to encoder is double-counted and larger than the accurate value. Libx264 encoding with B frames can also reproduce it. Signed-off-by: Zhong Li <zhong.li@intel.com>
