ipv4: nexthop: Remove unnecessary rtnl_dereference()

The pointer is not RCU protected, so remove the unnecessary
rtnl_dereference(). This suppresses the following warning:

net/ipv4/nexthop.c:1101:24: error: incompatible types in comparison expression (different address spaces):
net/ipv4/nexthop.c:1101:24:    struct rb_node [noderef] __rcu *
net/ipv4/nexthop.c:1101:24:    struct rb_node *
