avfilter/vf_minterpolate: Fix left shift of negative value

This has happened when initializing the motion estimation context if
width or height of the video was smaller than the block size used
for motion estimation and if the motion interpolation mode indicates
not to use motion estimation.

The solution is of course to only initialize the motion estimation
context if the interpolation mode uses motion estimation.
