This reverts commit 13d0955b250bcb7eac99034e7b1677d3d026b569.
Reason for revert:
this should be investigated further to ensure the memset is really
necessary outside of the static analysis pass.
Original change's description:
> vp9_loopfilter.c: zero lfl_uv
>
> The initialization depends on cm and mi_row which static
> analysis does not approve of.
>
> Clears a static analysis warning:
> warning: The right operand of '+' is a garbage value
> const loop_filter_thresh *lfi = lfthr + *lfl;
>
