Fix in first pass partition search

Fix to enable first pass partition search for complete superblocks in frame boundary.

For speed 1 and 2 presets, BD-rate drop is seen by 0.0226% and 0.0163% (as per AWCY runs)
with encode time reduction of 1.2% and 2% (averaged across multiple test cases) respectively.
