maple_tree: make test code work without debug enabled

Browse Source 
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.

Enable this option to test the maple tree code functions at boot, or
when the module is loaded. Enable "Debug Maple Trees" will enable
more verbose output on failures.
If unsure, say N.
