net/mlx5: Set interface flags before cleanup in unload_one

In load_one, the interface flags are changed from down to up,
only after initializing the interfaces.
In unload_one, the flags are changed from up to down before the
interface cleanup.

Change the cleanup order to be opposite to initialization order.

This fixes flag consistency between init and cleanup.
