[ Upstream commitf20ef34d71] Recent patch to prevent calling __nvme_fc_abort_outstanding_ios in interrupt context results in a possible race condition. A controller reset results in errored io completions, which schedules error work. The change of error work to a work element allows it to fire after the ctrl state transition to NVME_CTRL_CONNECTING, causing any outstanding io (used to initialize the controller) to fail and cause problems for connect_work. Add a state check to only schedule error work if not in the RESETTING state.

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.
