ice: replay advanced rules after reset

ice_replay_vsi_adv_rule will replay advanced rules for a given VSI.
Exit this function when list of rules for given recipe is empty.
Do not add rule when given vsi_handle does not match vsi_handle
from the rule info.

Use ICE_MAX_NUM_RECIPES instead of ICE_SW_LKUP_LAST in order to find
advanced rules as well.
