lavfi/deshake: fix deshake crash issue.
Fixes ticket #7441.
for block contrast calculate, the block is like this:
|<---------------- stride-----------------------|
+-----------------------------------------------> X
|
| w = 16
| (cx,cy)+------+
| | |
|h=blocksize| |
| | |
| +------+
V
Y
so we calc the block contrast use:
(cy + y) * stride + (cx + x)
