mlxsw: pci: Use napi_consume_skb() to free SKB as part of Tx completion

Currently, as part of Tx completion, the driver calls dev_kfree_skb_any()
to free the SKB. For this flow, the correct function is napi_consume_skb().
This function and dev_consume_skb_any() were added to be used for consumed
SKBs, which were not dropped, so the skb:kfree_skb tracepoint is not
triggered, and we can get better diagnostics about dropped packets.
