maple_tree: Make test code work without debug enabled

The test code is less useful without debug, but can still do general
validations.  Define mt_dump(), mas_dump() and mas_wr_dump() as a noop
if debug is not enabled and document it in the test module information
that more information can be obtained with another kernel config option.
