net/mlx5: fix secondary process resources release

When secondary process starts, it will allocate its own process private
data, and also does remap to UAR register of the Tx queue. Once the
secondary process exits, these resources should be released accordingly.
And the shared resources owned by primary should not be touched.

Currently, once one port in the secondary process spawn failed, all the
other spawned ports will also be released during process exits. However,
the mlx5_dev_close() function does not add the cases for secondary
process, it means call the mlx5_dev_close() function directly in
secondary process releases the resources it should not touch.

Add the case for secondary process release to its own resources in
mlx5_dev_close() function to help it quits gracefully.
