PCI: Fix device class print out
Found debug print of class is shifted.
| pci 0000:f8:15.2: [8086:2b56] type 0 class 0x000600
Code is trying to print class with 6 digits, but use shifted class with
4 digits valid value as variable.
Change to original dev->class directly.
Also remove not needed calculating of local variable class, because it
will be updated after pci_fixup_device(pci_fixup_early...)
Also unify type print out when class and header is not matched.
