The current code determines the last backing store valid type during bnxt_hwrm_func_backing_store_qcaps_v2(). In effect, the last type is determined based on what firmware advertises. The more correct way is to determine it based on what the driver is configuring. The driver may not configure all the backing store types advertised by firmware. Move the logic to determine the last type to bnxt_backing_store_cfg_v2(). We need to pass the legacy enable flags to the function in case only the legacy types are being configured.
