net/ice/base: correct argument port info

correct argument pi(port_info) passed in function
ice_sched_get_first_node(), otherwise it will return the incorrect
node.

functions ice_sched_get_agg_node and ice_sched_cfg_sibl_node_prio:
change argument from hw to pi for it to align to correct port.

Moved saving tc node bw info from hardware structure(hw) to port info
structure(pi). This change allows multiple ports to save and replay
the information correctly.
