From: Shay Drory <shayd@xxxxxxxxxx>
mlx5_irq_pool_get() is a getter for completion IRQ pool only.
However, after the cited commit, mlx5_irq_pool_get() is called during
ctrl IRQ release flow to retrieve the pool, resulting in the use of an
incorrect IRQ pool.
Hence, use the newly introduced mlx5_irq_get_pool() getter to retrieve
the correct IRQ pool based on the IRQ itself. While at it, rename
mlx5_irq_pool_get() to mlx5_irq_table_get_comp_irq_pool() which
accurately reflects its purpose and improves code readability.
