RDMA/hns: Fix the size setting error when copying CQE in clean_cq()
[ Upstream commit cc26aee100588a3f293921342a307b6309ace193 ]
The size of CQE is different for different versions of hardware, so the
driver needs to specify the size of CQE explicitly.
Fixes: 09a5f210f67e ("RDMA/hns: Add support for CQE in size of 64 Bytes")
