genX_mfd: fix calculation of motion vector mode
As stated in the PRM, the FastUVMCFlag field should be equal to the LSB
of the Motion Vector Mode field. This also conforms to VC-1 spec, as
FASTUVMC controls whether color difference motion vectors are
reconstructed with quarter of half pixel resolution.
