Zhao Zhili 670ff6c7ce avcodec/nvenc: rework on DTS generation 
Before the patch, the method to generate DTS only works with
timebase equal to 1/fps. With timebase like 1/1000

./ffmpeg -i foo.mp4 -an -c:v h264_nvenc -enc_time_base 1/1000 bar.mp4

pts 0    dts -3
pts 160  dts 37
pts 80   dts 77
pts 40   dts 117 <-- invalid
pts 120  dts 157
pts 320  dts 197
pts 240  dts 237
pts 200  dts 277 <-- invalid
pts 280  dts 317 <-- invalid

The generated DTS can be larger than PTS, since it only reorder the
input PTS and minus the number of frame delay, which doesn't take
timebase into account. It should minus the "time" of frame delay.

9a245bd trying to fix the issue, but the implementation is incomplete,
which only use time_base.num. Then it got reverted by ac7c265b33.

After this patch:

pts 0    dts -120
pts 160  dts -80
pts 80   dts -40
pts 40   dts 0
pts 120  dts 40
pts 320  dts 80
pts 240  dts 120
pts 200  dts 160
pts 280  dts 200
