RDMA/hns: Fix wrong value of max_sge_rd 

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IBSE4C



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

There is no sge difference between READ and non-READ operations in
hns RoCE. Set max_sge_rd to the same value as max_send_sge.
