net/mlx4_en: Don't use irq_affinity_notifier to track changes in IRQ affinity map
IRQ affinity notifier can only have a single notifier - cpu_rmap notifier. Can't use it to track changes in IRQ affinity map. Detect IRQ affinity changes by comparing CPU to current IRQ affinity map during NAPI poll thread.
