Fixes null pointer dereference
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

This fixes cases where the scantable permuation would get overwritten by
the general idctdsp initialization.

This makes the code about 1.5x faster without any noticeable difference
in the output.

This has no impact on overall performance, since the block DCT taking
most of the time anyway.

8x8 is about 5x faster than 16x16 on 1080p input. Since a block size of
8x8 makes the filter almost usable (time wise) and it's not obvious if
8x8 or 16x16 is better from a quality PoV (it really depends on the
input and parameters), the filter now defaults to 8x8, and as a result
libavfilter is micro bumped.
