[FFmpeg-devel] [PATCH 2/3] lavc/qsvenc: enlarge the maximum number of ExtParam buffers on mfxEncodeCtrl

[haihao.xiang-at-intel.com@ffmpeg.org]

From: Haihao Xiang <haihao.xiang@intel.com>

The next commit and other commits in future will use more ExtParam
buffers.

And combine 2 free functions into single one
