RDMA/hns: Fix the modification of max_send_sge 

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IB30V8



----------------------------------------------------------------------

The attribute max_send_sge describes the requested max number of
SGE in a WR in the SQ. It is a necessary attribute for creating
a qp. It is returned directly without modifying its value.

Fixes: 0c5e259b ("RDMA/hns: Fix incorrect sge nums calculation")
