hevc: only write to max_ra and pocTid0 in the first slice.
Values from subsequent values are guaranteed to be identical (since poc and nal_unit_type are checked to be the same between slices), so this doesn't affect output in any way, but does resolve the remaining reported race conditions (by tsan) in fate-hevc. In practice, this fixes tsan warnings like this: WARNING: ThreadSanitizer: data race (pid=25334) Read of size 4 at 0x7d9c0001adcc by main thread (mutexes: write M1386): #0 hevc_update_thread_context src/libavcodec/hevcdec.c:3310 (ffmpeg+0x000000b41c7c) [..] Previous write of size 4 at 0x7d9c0001adcc by thread T1 (mutexes: write M1383): #0 hls_slice_header src/libavcodec/hevcdec.c:596 (ffmpeg+0x000000b43a22) (cherry picked from commit 1f50baa2b2da7fdbfccf0662883f38a763ff6619) Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
