net/mlx5: fix freeing packet pacing

[ upstream commit b492e28 ]

Packet pacing is allocated under condition #ifdef HAVE_MLX5DV_PP_ALLOC.
In a similar way - free packet pacing index under the same condition.
This update is required to successfully compile under operating systems
which do not support packet pacing.
