maple_tree: add __init and __exit to test module

[ Upstream commit eaf9790d3bc6e157a2134c01c7d707a5a712fab1 ]

The test functions are not needed after the module is removed, so mark
them as such.  Add __exit to the module removal function.  Some other
variables have been marked as const static as well.
