Subject: [PATCH] net/mlx5: fix drop queue creation error

[ upstream commit b98b61c308f84eaf82977db6fbd792775486e4c1 ]

Creating a drop queue in mlx5 ends by creating a non polled queue, but if
the associated work queue could not be created the error was not handled
ending in a undefined situation.

Fixes: 2097d0d1e2cc ("net/mlx5: support basic flow items and actions")
