net/mlx5: HWS, Fix pool size optimization

Browse Source 
The optimization to create a size-one STE range for the unused direction
was broken. The hardware prevents us from creating RTCs over unallocated
STE space, so the only reason this has worked so far is because the
optimization was never used.
