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.
MT_BUG_ON() will report a failures without tree dumps, and the output
will be less useful.
