Subject: [PATCH rdma-next v1 1/9] RDMA/hns: Don't skip IB creation flow for regular RC QP

From: Leon Romanovsky <leonro@...dia.com>

The call to internal QP creation function skips QP creation checks
and misses the addition of such device QPs to the restrack DB.

As a preparation to general allocation scheme, convert hns to use
proper API.
