Do not emit debug printfs under NODEBUG

These printfs spew to the console when command-line utilities
such as 'klist' and 'aklog' are run, reducing usability.

These printfs can also cause application hangs.
On a multiprocessor machine, when PuTTY and the ccapiserver are
running on different CPUs, PuTTY appears to deadlock with three
concurrent threads inside cci_debug_printf().
