commit 1f85d58cdf15354a7120fc9ccc9bb9c45b53af88
cnic: Remove uio mem[0].
introduced a regression as older versions of userspace app still rely
on this mmap. Restore the mmap functionality and get the base address
from pci_resource_start() as the nedev->base_addr has been deprecated for
PCI devices.
Update version to 2.5.12.
