ipv6: Refactor find_rr_leaf
find_rr_leaf has 3 loops over fib_entries calling find_match. The loops
are very similar with differences in start point and whether the metric
is evaluated:
1. start at rr_head, no extra loop compare, check fib metric
2. start at leaf, compare rt against rr_head, check metric
3. start at cont (potential saved point from earlier loops), no
extra loop compare, no metric check
Create 1 loop that is called 3 different times. This will make a
later change with multipath nexthop objects much simpler.
