Remove avoid_frame_with_high_error from RD loop

The feature undergoes prior assumption that the recursive partition
size search from 4x4 to 64x64, hence utilizing information from small
blocks to determine early termination in large block rate-distortion
optimization search. The current codebase is now going from top down.
The previous function might go with not properly initialized values,
hence removed.

Tested on pedestrian_area_1080p at 4000 kbps running under speed 2.
No visible difference in runtime observed.

The code can be removed because mvp_full will be overridden after that.
