RDMA/mlx5: Remove raw RSS QP restrack tracking

Raw RSS QP restrack tracking wasn't working to begin with as it was
only tracking the first raw RSS QP which was added, since at creation
the raw RSS QP number is reserved so the QP number for this qp type
was always zero.
The following raw RSS QP additions were always failing silently.

Since the fix isn't trivial and there were no users that required or
complained about this issue we are dropping this for now instead of fixing.
