net/mlx5: Fix build break when CONFIG_SMP=n
[ Upstream commit e3ca34880652250f524022ad89e516f8ba9a805b ]
Avoid using the kernel's irq_descriptor and return IRQ vector affinity
directly from the driver.
This fixes the following build break when CONFIG_SMP=n
include/linux/mlx5/driver.h: In function ‘mlx5_get_vector_affinity_hint’:
include/linux/mlx5/driver.h:1299:13: error:
‘struct irq_desc’ has no member named ‘affinity_hint’
Fixes: 6082d9c9c94a ("net/mlx5: Fix mlx5_get_vector_affinity function")
