avfilter/avfiltergraph: fix -Wunused-result warnings
Commit bf0d2d6030c239f91e0368a20fb2dc0705bfec99 introduced
av_warn_unused_result to avfilter/formats, whose associated warnings
were mostly fixed in 6aaac24d72a7da631173209841a3944fcb4a3309. This
fixes the issues in avfilter/avfiltergraph.
Tested with FATE.
