pci-devfn: check that device/slot number is within range
Need to check that guest slot/device number is not > 31 or walk off the devfn table when checking if a devfn is available or not in a guest. before this fix, passing in an addr=abc or addr=34, can crash qemu, sometimes fail gracefully if data past end of devfn table fails the availability test. with this fix, get clean error: Property 'pci-assign.addr' doesn't take value '34' also tested when no addr= param passed for guest (pcicfg) address, and that worked as well.
