Limit the maximal queue size for RDMA controllers. Today, the target reports a limit of 1024 and this limit isn't valid for some of the RDMA based controllers. For now, limit RDMA transport to 128 entries (the max queue depth configured for Linux NVMe/RDMA host). Future general solution should use RDMA/core API to calculate this size according to device capabilities and number of WRs needed per NVMe IO request.
