[PATCH v3 1/6] common/mlx5: consider local functions as internal

[Michael Baum <michaelba@nvidia.com>]

The functions which are not explicitly marked as internal
were exported because the local catch-all rule was missing in the
version script.
After adding the missing rule, all local functions are hidden.
The function mlx5_get_device_guid is used in another library,
so it needs to be exported (as internal).

Because the local functions were exported as non-internal
in DPDK 21.11, any change in these functions would break the ABI.
An ABI exception is added for this library, considering that all
functions are either local or internal.
