When reconnecting, the request may be completed with NVME_SC_HOST_PATH_ERROR in nvmf_fail_nonready_command, which currently set the state of the request to MQ_RQ_IN_FLIGHT before calling nvme_complete_rq. When this happens for a request that is freed by the caller, such as nvme_submit_user_cmd, in the worst case the request could be completed again in tear down process. Instead of calling blk_mq_start_request from nvmf_fail_nonready_command, just use the new nvme_host_path_error helper to complete the command without starting 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.
