Keith Busch cb9e0e5006 nvme-pci: use blk-mq mapping for unmanaged irqs 
If a device is providing a single IRQ vector, the IO queue will share
that vector with the admin queue. This is an unmanaged vector, so does
not have a valid PCI IRQ affinity. Avoid trying to extract a managed
affinity in this case and let blk-mq set up the cpu:queue mapping instead.
Otherwise we'd hit the following warning when the device is using MSI:

 WARNING: CPU: 4 PID: 7 at drivers/pci/msi.c:1272 pci_irq_get_affinity+0x66/0x80
