avfilter/vf_ssim360: Use correct type in sizeof SSIM360Context.ssim360_hist is an array of four pointers to double; so sizeof(*ssim360_hist[0]) (=sizeof(double)) is the correct size to use to calculate the amount of memory to allocate, not sizeof(*ssim360_hist) (which is sizeof(double*)). Use FF_ALLOCZ_TYPED_ARRAY to avoid this issue altogether. Fixes Coverity issue #1520671.
