net/mlx4_en: Don't use irq_affinity_notifier to track changes in IRQ affinity map

Browse source

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.
