By binding device finding with create QP logic to fix the bug of creating
QP failure occasionally. Then, merge the find device related code into
qm.c to reduce redundancy.

From: Weili Qian <qianweili@huawei.com>
Use struct hisi_qm to maintain device list. Meanwhile, add two external
interface into qm, merge find proper device and create qp into QP alloc
logic, merge release qps into QP free logic.

Encapsulate hisi_qm_alloc_qps_node() to new interface to replace
find_zip_device(), which will fix the bug of creating QP failure
especially in multi-thread scenario.

From: Kai Ye <yekai13@huawei.com>
Combine found device and created qp into one operation instead of found
device and create qp both are independent operations. when execute
multiple tasks, the different threads may find same device at the same
time, but the number of queues is insufficient on the device. causing
one of threads fail to create a qp. Now fix this, First find device then
create qp, if result failure. the current thread will find next device.
