The meter policy handlers are managed by user IDs and the driver used l3
table in order to map the user ID to the internal driver handler of the
policy.

The l3 table was wrongly saved in the shared device structure which
manages all the switch domain ports what made the user IDs shared
between different ethdev ports.

Move the policy l3 table to be per port by saving it in the port private
structure.

Fixes: afb4aa4f122 ("net/mlx5: support meter policy operations")
