Remove redundant comparison of `fav_factor` in `update_bitmap_score`
`top_rated_fav_factor` was actually calculated twice,
but only one calculation and comparison is needed.

Since `fav_factor` > `top_rated_fav_factor` will always cause skip of current
iteration, `else if (fuzz_p2 == top_rated_fuzz_p2)` is also redundant.
