RE: [PATCH v2 1/2] common/mlx5: fix build disabling

[Matan Azrad]

> If the dependency common/mlx5 is explicitly disabled, but net/mlx5 is not
> explicitly disabled, Meson will read the full recipe of net/mlx5 and will fail
> when accessing a variable from common/mlx5:
> drivers/net/mlx5/meson.build:76:4: ERROR: Unknown variable
> "mlx5_config".
> 
> The solution is to stop parsing net/mlx5 if common/mlx5 is disabled.
> The deps array must be defined before stopping, in order to automatically
> disable the build of net/mlx5 and print the reason.
> 
> The same protection is applied to other mlx5 drivers, so it will allow using 
> the
> variable mlx5_config in future.
