Dom0 PCI: fix a regression introduced by the SR-IOV change

The device class may be changed during the early fixup. So need to
re-read the device class from pci_dev after the fixup.

The patch "PCI: centralize device setup code" (c/s 825) wrongly
cleaned up the device class re-read. This patch reverts that change.
