ip: nexthop: split print_nh_res_group into parse and print parts 

Now that we have resilient group structure split print_nh_res_group into
a parse and print functions, print_nexthop calls the parse function
first to parse the attributes into the structure and then uses the print
function to print the parsed structure.
