Lang Cheng 62490fd5a8 RDMA/hns: Avoid unnecessary memset on WQEs in post_send 
All fields of WQE will be rewrote, so the memset is unnecessary. And when
SQ is working in OWNER mode, the pipeline may prefetch the WQEs beyond PI,
the memset operation may flip the owner bit too early, then the pipeline
may get a wrong WQ.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
