avfilter/vf_minterpolate: Remove redundant code for freeing
...
ad73b32d29
added some code for freeing in
the input's config_props function, yet this is unnecessary as uninit is
called anyway if config_props fails.

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.

avfilter/vf_minterpolate: Reject too small dimensions
...
The latter code relies upon the dimensions to be not too small;
otherwise one will call av_clip() with min > max lateron which aborts
in case ASSERT_LEVEL is >= 2 or one will get a nonsense result that may
lead to a heap-buffer-overflow/underflow. The latter has happened in
ticket #8248 which this commit fixes.

The results are consistent with tests/ref/fate/filter-metadata-scenedetect
For the master, it'll detect more than 20 scene change for the same source.
