ionic: improve irq numa locality

Browse source

Spreading the interrupts across the CPU cores is good for load
balancing, but not necessarily as good when using a CPU/core
that is not part of the NUMA local CPU.  If it can be localized,
the kernel's cpumask_local_spread() service will pick a core
that is on the node close to the PCI device.
