avcodec/nvenc: fix hw accelerated transcode with bframes
hw accelerated transcode (h264_cuvid -> h264_nvenc with -hwaccel cuvid) was
broken after the filtergraph initialization was changed to intialize decoder
first followed by encoder (commit af1761f7b5b1b72197dc40934953b775c2d951cc).
During initialzing encoder with bframes, local buffers are allocated
internally in encoder which fails since no cuda context is available. Now
pushing the correct cuda context before encoder initialization fixes the issue.
Also adding push/pop cuda ctx during create/destroy/map/unmap resources and
destroy encoder session.
