[PATCH] net/mlx5: fix masked indirect age action validation

[Dariusz Sosnowski]

Masked indirect age flow action is not supported in
actions templates.
Up to this patch, this case was checked only through
debug assertion. As a side effect, in a build without assertions,
this lead to a segfault on the attempt to create
a table using actions template with masked indirect age action.
To prevent the segfault, this patch adds relevant validation
to actions template creation and removes the debug assertion
which now becomes redundant.
