nvh265sldec: Sync up with d3d11h265dec implementation

Browse source 
Each RefPicSetStCurrBefore/RefPicSetStCurrAfter/RefPicSetLtCurr array
might have empty element (i.e., reference pictures might not be stored
sequentially). Don't error out for the empty element case,
but instead, iterates each array and fill NVDEC's reference list
as much as possible
