ipv4: Add fib_nh_common to fib_result
Most of the ipv4 code only needs data from fib_nh_common. Add
fib_nh_common selection to fib_result and update users to use it.
Right now, fib_nh_common in fib_result will point to a fib_nh struct
that is embedded within a fib_info:
fib_info --> fib_nh
fib_nh
...
fib_nh
^
fib_result->nhc ----+
Later, nhc can point to a fib_nh within a nexthop struct:
fib_info --> nexthop --> fib_nh
^
fib_result->nhc ---------------+
or for a nexthop group:
fib_info --> nexthop --> nexthop --> fib_nh
nexthop --> fib_nh
...
nexthop --> fib_nh
^
fib_result->nhc ---------------------------+
In all cases nhsel within fib_result will point to which leg in the
multipath route is used.
