Will set lat buffer to lat_list two times when lat decode timeout for
inner racing mode.
If core thread can't get frame buffer, need to return error value.

If you're jumping to vdec_dec_end, this check becomes pointless as y_fb_dma
will never be set to 0, so you can remove the conditional on assigning
the dma address to `y_fb_dma`.
Same comment a few lines later for `c_fb_dma`.
