    Fixed DXVA_Slice_H264_Long::BitOffsetToSliceData value.
    
    The 8 bits offset (nal unit type) should not be added, as the spec says:
    
    "This bit offset is the offset within the RBSP data for the slice, relative
    to the starting position of the slice_header() in the RBSP"
    
    This fixes DXVA2 support for intel GPU.
