In udp_v4/6_early_demux() code, we try to hold dst->__refcnt for dst with DST_NOCACHE flag. This is because later in udp_sk_rx_dst_set() function, we will try to cache this dst in sk for connected case. However, a better way to achieve this is to not try to hold dst in early_demux(), but in udp_sk_rx_dst_set(), call dst_hold_safe(). This approach is also more consistant with how tcp is handling it. And it will make later changes simpler. Signed-off-by:
