mlxsw: spectrum_ipip: Split accessor functions
To implement NETDEV_CHANGE notifications on IP-in-IP tunnels, the handler needs to figure out what actually changed, to understand how exactly to update the offloads. It will do so by storing struct ip_tunnel_parm with previous configuration, and comparing that to the new version. To facilitate these comparisons, extract the code that operates on struct ip_tunnel_parm from the existing accessor functions, and make those a thin wrapper that extracts tunnel parameters and dispatches.
