avformat/nutenc: Do not pass NULL to memcmp() in get_needed_flags()
This compared to the other suggestions is cleaner and easier to understand
keeping the condition in the if() simple.
This affects alot of fate tests.
See: [FFmpeg-devel] [PATCH 05/11] avformat/nutenc: Don't pass NULL to memcmp
See: [FFmpeg-devel] [PATCH]lavf/nutenc: Do not call memcmp() with NULL argument
