efi/cper: Fix endianness of PCIe class code
The CPER parser assumes that the class code is big endian, but at least
on this edk2-derived Intel Purley platform it's little endian:
efi: EFI v2.50 by EDK II BIOS ID:PLYDCRB1.86B.0119.R05.1701181843
DMI: Intel Corporation PURLEY/PURLEY, BIOS PLYDCRB1.86B.0119.R05.1701181843 01/18/2017
{1}[Hardware Error]: device_id: 0000:5d:00.0
{1}[Hardware Error]: slot: 0
{1}[Hardware Error]: secondary_bus: 0x5e
{1}[Hardware Error]: vendor_id: 0x8086, device_id: 0x2030
{1}[Hardware Error]: class_code: 000406
^^^^^^ (should be 060400)
