The current behavior is intended like it is.
On the default of -1, it does not care about I/IDR frame requests, in
mode 0 it will generate intra frames, and in mode 1 it will generate
full IDR frames.

This is not clever, because i checked both libx264 and libx265 and both
of them has same behavior like i proposed in patch.
Also explanation of this function is than wrong:
{ "forced-idr", "If forcing keyframes, force them as IDR frames."}
There is nothing about disabled forcing keyframes at all.
So we have two options:
1. We should change it in NVENC
or
2. We should change it in libx264 and libx265
Changing it in nvenc now would be kind of an API break, as the behaviour
might change without someone expecting it.

I don't think so, onlything is changed is when you forcing keyframes
with -forced_keyframes option it was not working in NVENC without
specifiing -force_idr 0 or 1, is there any other situation when some
parts of ffmpeg will force key frames and NVENC naturaly ignore them?
