Subject: ipv6: remove the unnecessary statement in find_match()

ipv6: remove the unnecessary statement in find_match()

After reading the function rt6_check_neigh(), we can
know that the RT6_NUD_FAIL_SOFT can be returned only
when the IS_ENABLE(CONFIG_IPV6_ROUTER_PREF) is false.
so in function find_match(), there is no need to execute
the statement !IS_ENABLED(CONFIG_IPV6_ROUTER_PREF).
