werror: fix pci calgary
Fix an integer comparison always false warning in the PCI Calgary 64 driver. A u8 is being compared to something that's 512 by default, resulting in the following warning: arch/x86/kernel/pci-calgary_64.c:1285: warning: comparison is always false due to limited range of data type This was introduced by patch b34e90b8f0f30151349134f87b5dc6ef75a5218c.
