Restoring maple status to ma_active on overflow/underflow when mas->node was NULL could have happened in the past, but was masked by a bug in mas_walk(). Add test cases that triggered the bug when the node was mas->node prior to fixing the maple state setup. Add a few extra tests around restoring the active maple status.

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.
