Lang Cheng 292b3352bd RDMA/hns: Adjust fields and variables about CMDQ tail/head
The register 0x07014 is actually the head pointer of CMDQ, and 0x07010
means tail pointer. Current definitions are confusing, so rename them and
related variables.

The next_to_use of structure hns_roce_v2_cmq_ring has the same semantics
as head, merge them into one member. The next_to_clean of structure
hns_roce_v2_cmq_ring has the same semantics as tail. After deleting
next_to_clean, tail should also be deleted.
