[SCSI] bnx2i: Removed the reference to the netdev->base_addr
The netdev->base_addr parameter has been deprecated in the L2 bnx2 driver. This is used by bnx2i for the BARn iomapping. This patch will directly reference the pci_resource_start instead of using the deprecated netdev->base_addr. This patch is actually a critical bug fix as the 1G bnx2 driver no longer supports the netdev->base_addr in the current kernel of the scsi tree. This means that Broadcom's 1G Linux iSCSI offload solution would not work at all without this patch.
