test_maple_tree: test exhausted upper limit of mtree_alloc_cyclic()
When the upper bound of the search is exhausted, the maple state may be
returned in an error state of -EBUSY. This means maple state needs to be
reset before the second search in mas_alloc_cylic() to ensure the search
happens. This test ensures the issue is not recreated.
