net: socionext: netsec: fix xdp stats accounting

Browse source 
Increment netdev rx counters even for XDP_DROP verdict. Report even
tx bytes for xdp buffers (TYPE_NETSEC_XDP_TX or TYPE_NETSEC_XDP_NDO).
Moreover account pending buffer length in netsec_xdp_queue_one as it is
done for skb counterpart
