Chao Leng a87da50f39 nvme-rdma: fix crash due to incorrect cqe
A crash happened due to injecting error test.
When a CQE has incorrect command id due do an error injection, the host
may find a request which is already freed.  Dereferencing req->mr->rkey
causes a crash in nvme_rdma_process_nvme_rsp because the mr is already
freed.

Add a check for the mr to fix it.

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.
