net/mlx5: Synchronize correct IRQ when destroying CQ
[ Upstream commit 563476ae0c5e48a028cbfa38fa9d2fc0418eb88f ]
The CQ destroy is performed based on the IRQ number that is stored in
cq->irqn. That number wasn't set explicitly during CQ creation and as
expected some of the API users of mlx5_core_create_cq() forgot to update
it.
This caused to wrong synchronization call of the wrong IRQ with a number
0 instead of the real one.
As a fix, set the IRQ number directly in the mlx5_core_create_cq() and
update all users accordingly.
Fixes: 1a86b377aa21 ("vdpa/mlx5: Add VDPA driver for supported mlx5 devices")
Fixes: ef1659ade359 ("IB/mlx5: Add DEVX support for CQ events")
