ice: Remove unused members from switch API

Browse Source 
Remove several members of struct ice_sw_recipe and struct
ice_prot_lkup_ext. Remove struct ice_recp_grp_entry and struct
ice_pref_recipe_group, since they are now unused as well.

All of the deleted members were only written to and never read, so it's
pointless to keep them.
