In the extent map self tests, when freeing all extent maps from a test extent map tree we are not expecting to find any extent map with a reference count different from 1 (the tree reference). If we find any, we just log a message but we don't fail the test, which makes it very easy to miss any bug/regression - no one reads the test messages unless a test fails. So change the behaviour to make a test fail if we find an extent map in the tree with a reference count different from 1. Make the failure happen only after removing all extent maps, so that we don't leak memory.

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 reStructuredText 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.
