[PATCH 3/3] nvme: allocate queues for all possible CPUs

[Christoph Hellwig]

Unlike most drіvers that simply pass the maximum possible vectors to
pci_alloc_irq_vectors NVMe needs to configure the device before allocting
the vectors, so it needs a manual update for the new scheme of using
all present CPUs.
