In resource_test_insert_resource(), the pointer is used in error message
after kfree(). This is user-after-free. To fix this, we need to call
kunit_add_action_or_reset() to schedule memory freeing after usage. But
kunit_add_action_or_reset() itself may fail and free the memory. So, its
return value should be checked and abort the test for failure. Then, we
found that other usage of kunit_add_action_or_reset() in
resource_test_region_intersects() needs to be fixed too. We fix all these
user-after-free bugs in this patch.

README
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.
