This driver has several pieces of dead code (found by running
make namespacecheck). This patch removes them.

qlcnic driver allocates rx skbs and gives to hardware too bytes of extra
storage, allowing for corruption of kernel data.
NET_IP_ALIGN being 0 on some platforms (including x86), drivers should
not assume it's 2.
rds_ring->skb_size = rds_ring->dma_size + NET_IP_ALIGN;
...
skb = dev_alloc_skb(rds_ring->skb_size);
skb_reserve(skb, 2);
pci_map_single(pdev, skb->data, rds_ring->dma_size, PCI_DMA_FROMDEVICE);
(and rds_ring->skb_size == rds_ring->dma_size) -> bug
Because of extra alignment (1500 + 32) -> four extra bytes are available
before the struct skb_shared_info, so corruption is not noticed.
Note: this driver could use netdev_alloc_skb_ip_align()

We can avoid setting again skb->ip_summed to CHECKSUM_NONE in drivers.
Introduce skb_checksum_none_assert() helper so that we keep this
