Subject: [PATCH 3/3] libhns: Disable local invalidate operation

mainline inclusion
commit d8eec872
category: bugfix
bugzilla: https://gitee.com/src-openeuler/rdma-core/issues/I72F0U
CVE: NA

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

Currently local invalidate operation don't work properly.
Disable it for the time being.
HIP08 and HIP09 hardware does not support this feature, so
delete the associated code.

Fixes: a9ae7e9bfb5d ("libhns: Add local invalidate MR support for hip08")
