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.
