net/ice/base: refactor VSI node scheduler

Refactored VSI node sched code to use port_info ptr as call arg.

The declaration of VSI node getter function has been modified to use
pointer to ice_port_info structure instead of pointer to hw structure.
This way suitable port_info structure is used to find VSI node.
