net/mlx5: Remove redundant bw_share minimal value assignment
Remove unnecessary logic that sets bw_share to minimal value, when
parent has bw_share configured but nodes don't have min_rate.
This check is redundant because the parent bandwidth acts as the upper
bound regardless, and the firmware always enforces the topmost
bandwidth constraint.
