ice: Adjust scheduler default BW weight 

By default the queues are configured in legacy mode. The default
BW settings for legacy/advanced modes are different. The existing
code was using the advanced mode default value of 1 which was
incorrect. This caused the unbalanced BW sharing among siblings.
The recommended default value is applied.
