Ensure that IRQ affinity setup also respects the queue-to-CPU mapping constraints provided by the block layer. This allows the SCSI drivers to avoid assigning interrupts to CPUs that the block layer has excluded (e.g., isolated CPUs). Only convert drivers which are already using the pci_alloc_irq_vectors_affinity with the PCI_IRQ_AFFINITY flag set. Because these drivers are enabled to let the IRQ core code to set the affinity. Also don't update qla2xxx because the nvme-fabrics code is not ready yet.
