nexthop: Do not increment dump sentinel at the end of the dump
The nexthop and nexthop bucket dump callbacks previously returned a positive return code even when the dump was complete, prompting the core netlink code to invoke the callback again, until returning zero. Zero was only returned by these callbacks when no information was filled in the provided skb, which was achieved by incrementing the dump sentinel at the end of the dump beyond the ID of the last nexthop. This is no longer necessary as when the dump is complete these callbacks return zero. Remove the unnecessary increment.
