ice: move VSI delete outside deconfig
In deconfig VSI shouldn't be deleted from hw. Rewrite VSI delete function to reflect that sometimes it is only needed to remove VSI from hw without freeing the memory: ice_vsi_delete() -> delete from HW and free memory ice_vsi_delete_from_hw() -> delete only from HW Value returned from ice_vsi_free() is never used. Change return type to void.
