ipv4: nexthop: avoid duplicate NHA_HW_STATS_ENABLE on nexthop group dump

Currently NHA_HW_STATS_ENABLE is included twice everytime a dump of
nexthop group is performed with NHA_OP_FLAG_DUMP_STATS. As all the stats
querying were moved to nla_put_nh_group_stats(), leave only that
instance of the attribute querying.
