It seems that various things can trigger the lr cleanup worker, including CAT error, engine reset and destroying the actual engine, so seems plausible to end up triggering the worker more than once in some cases. If that does happen we can race with an ongoing engine deregister before it has completed, thus triggering it again and also changing the state back into pending_disable. Checking if the engine has been marked as destroyed looks like it should prevent this.

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.
