nvenc: Minimize the surface allocation
...
The previous default sets the allocated surfaces to 32 unless it is
user-overridden or the lookahead parameter is set.
Change the surfaces calculation for default, B-frames and lookahead scenario.

nvenc: Add default value for AVCodecContext::refs
...
AVCodecContext::refs is used to control the DPB size to be used by the
encoder. The default value for AVCodecContext::refs as set in
libavcodec/options_table.h is 1.
This patch sets AVCodecContext::refs to 0 for h264_nvenc and hevc_nvenc in
order to let the driver take the decision of the correct DPB size to use in
all cases.
