maple_tree: add test to replicate low memory race conditions
Add new callback fields to the userspace implementation of struct
kmem_cache. This allows for executing callback functions in order to
further test low memory scenarios where node allocation is retried.
This callback can help test race conditions by calling a function when a
low memory event is tested.
