NVMe: fail pci initialization if the device doesn't have any BARs The PCI init of NVMe doesn't check for valid bars before proceeding to map and use BAR 0. If the device is hosed (or firmware is), then we should catch this case and give up early. This fixes a: [ 1662.035778] WARNING: CPU: 0 PID: 4 at arch/x86/mm/ioremap.c:63 __ioremap_check_ram+0xa7/0xc0() and later badness on such a device.
