[PATCH for-next 5/9] RDMA/hns: Fix cast from or to restricted __le32 for driver

[Lijun Ou <oulijun@huawei.com>]

From: Lang Cheng <chenglang@huawei.com>

Sparse is whining about the u32 and __le32 mixed usage in the driver.
The roce_set_field() is used to __le32 data of hardware only.
If a variable is not delivered to the hardware, the __le32 type and
related operations are not required.
