net/mlx4_core: Fix to clean devlink resources
This patch cleans devlink resources by calling devlink_port_unregister()
to avoid the following issues:
- Kernel panic when triggering reset flow.
- Memory leak due to unfreed resources in mlx4_init_port_info().
Fixes: 09d4d087cd48 ("mlx4: Implement devlink interface")
