Fix a regression introduced by commit 35f6f45 ("net/mlx4_en: Don't use irq_affinity_notifier to track changes in IRQ affinity map"). When core is started in legacy EQ's (number of IRQ's < rx rings), cq->irq_desc was NULL. This caused a kernel crash under heavy traffic - when having more than rx NAPI budget completions. Fixed to have it set for both EQ modes.
