IB/ipath: Use pci_dev->revision, again

Commit 44c10138fd4b ("PCI: Change all drivers to use pci_device->revision")
already converted this driver to using the revision field of struct
pci_dev but commit bb9171448deb ("IB/ipath: Misc changes to prepare
for IB7220 introduction") later reverted that change for some strange
reason.  Restore the change.
