RDMA/hns: Fix wrong value of max_sge_rd 

maillist inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IBV0G0
CVE: NA

Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git/commit/?h=wip/leon-for-rc&id=6b5e41a8b51fce520bb09bd651a29ef495e990de



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

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