genirq: Provide !SMP stub for irq_set_affinity_notifier()

Instead of requiring each consumer of the IRQ affinity notifier to have
themselves be explicitly dependent on CONFIG_SMP, make the definition of
struct irq_affinity_notify to exist independently of that config option
and introduce a stub for irq_set_affinity_notifier() under non SMP
configuration.

Fixes: 2eacc23 ("net/mlx4_core: Enforce irq affinity changes
immediatly")
