VPU: return correct decoded length on iommu case

On iommu case the decode buffer address is replace by iommu address.
When decoding finished the new register value is also the iommu address.
So the actual decoded length need a hack to calculate.

This patch is to resolve H.264 field stream packet with both top field
and bottom field. By retrieving the real decoded length decoder can detect
this case.
