avcodec/hevcdec: fix segfault on invalid film grain metadata
Invalid input files may contain film grain metadata which survives
ff_h274_film_grain_params_supported() but does not pass
av_film_grain_params_select(), leading to a SIGSEGV on hevc_frame_end().
Fix this by duplicating the av_film_grain_params_select() check at frame
init time.
An alternative solution here would be to defer the incompatibility check
to hevc_frame_end(), but this has the downside of allocating a film
grain buffer even when we already know we can't apply film grain.
Fixes: https://trac.ffmpeg.org/ticket/10951
