[PATCH V4 for-next 01/14] RDMA/hns: Encapsulate some lines for setting sq size in user mode

[Lijun Ou <oulijun@huawei.com>]

It needs to check the sq size with integrity when configures
the relatived parameters of sq. Here moves the relatived code
into a special function.

V3->V4:
1. Remove replace operation for the origin dev print interface.

V1->V2:
1. Use the new print interface according to Gal Pressman because it
   can print the detail ib_device name
