When setting up a new extent map, at setup_extent_mapping(), we're doing a list move operation to add the extent map the tree's list of modified extents. This is confusing because at this point the extent map can not be in any list, because it's a new extent map. So replace the list move with a list add and add an assertion that checks that the extent map is not currently in any list.

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.
