    Fix huawei driver test issues

    Replace "params[params.index('-lun')]" with
    "params[params.index('-lun') + 1]" to get lun ID correctly.
    Replace the invalid controller ID "N" with "B".
    Dict CLONED_LUN_INFO has no key provider_location, delete it.

    Moreover, simplify the "if..., elif..." module with "getattr"
    method in fake recv function.

    fixes bug 1225884
