Fix the model for 4-partition pruning

The source pixel variance calculation was done incorrectly as the buffer
pointer was not set properly. This patch fixes it and updates the
model with re-trained weights.

Coding performance changes(30 frames):
            lowres      midres
speed 0     0.012%     -0.017%
speed 1     0.016%      0.057%

Tested encoding speed with QP=40 speed 1 on some lowres clips,
speed gains: maximum 13%; average 4%.
