msdk: jpegdec: Fix non-interleaved sample decode

Browse source 
Using the default value (InterleavedDec == MFX_SCANTYPE_UNKNOWN)
causing issues with non-interleaved sample decode. Ideally the usage
of MFXVideoDECODE_DecodeHeader should fix these type of issue, but
it seems to be not. But hardcoding the InterleaveDec to
MFX_SCANTYPE_NONINTERLEAVED
is fixing the problem and fortunately msdk seems to be taking care of
Interleaved samples
too .So let's hardcode it for now.
