[PATCH net-next V2 05/12] net/mlx5: HWS, Cleanup after pool refactoring

[Tariq Toukan <tariqt@nvidia.com>]

From: Vlad Dogaru <vdogaru@nvidia.com>

Remove members which are now no longer used. In fact, many of the
`struct mlx5hws_pool_chunk` were not even written to beyond being
initialized, but they were used in various internals.

Also cleanup some local variables which made more sense when the API was
thicker.
