Remove unneeded push to winner_mode_stats for kfs
In the current codebase, we push a winner_mode_stat with the current
best_rd before we start trying any prediction mode. However, an invalid
mbmi is also pushed to the list of winner_mode_stats, which results in
some extra WINNER_MODE_EVAL in multi-winner mode.
This commit removes the initial push to winner_mode_stats in for kfs.
