In case rdma accept fails at nvmet_rdma_queue_connect(), release work is scheduled. Later on, a new RDMA CM event may arrive since we didn't destroy the cm-id and call nvmet_rdma_queue_connect_fail(), which schedule another release work. This will cause calling nvmet_rdma_free_queue twice. To fix this we implicitly destroy the cm_id with non-zero ret code, which guarantees that new rdma_cm events will not arrive afterwards. Also add a qp pointer to nvmet_rdma_queue structure, so we can use it when the cm_id pointer is NULL or was destroyed.

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.
