[FFmpeg-cvslog] dxva: fix some warnings

[wm4]

ffmpeg | branch: master | wm4 <nfxjfg at googlemail.com> | Thu Jun 22 14:52:53 2017 +0200| [39f201a0ec7913f7509a01fb0fa6634a24e52203] | committer: wm4

dxva: fix some warnings

Some existed since forever, some are new.

The cast in get_surface() is silly, but unless we change the av_log
function signature, or all callers of ff_dxva2_get_surface_index(), it's
needed to remove the const warning.

Merges Libav commit 752ddb45569ffe278393cd853b70f18ae017219e.
