default_ref[] is unconditionally initialized in h264_initialise_ref_list()
(called from ff_h264_build_ref_list(), called from h264_slice_init()).
This fixes the following tsan warning when running fate-h264:

@fpzeng 您好，我参考《H.265 RTMP推流使用指南》上的方法，用libx265推了一个rtmp流，但ffplay播放时报错
[AVBSFContext @ 0x7fd6540b1f20] No start code is found. 0B f=0/0
rtmp://192.168.1.100/live/h265: could not find codec parameters
但若用libx264推流就没有问题。RTMP服务器我用的是nginx-rtmp-module, ffplay用的金山云ffmpeg编译的。另外，我还试了下ks-webplayer，也无法播放h265的rtmp流。请教下这该怎么解决呢？
万分感谢！
