code cleanup: remove unused debug_printk()

The dahdi_echocan_* modules had an unused debug_printk() macro. Remove
them because:

* They were unused
* There were multiple definitions
* They were unsafe. Someone doing an
    if(foo)
      debug_printk(...);
    else
      do_something();
  may be surprised ;-)
* They used 'debug' as a debug level, while the rest of DAHDI debug
  macros treat it as a bit-field.

Leave only a single definition in wcte12xp/base.c which is safe.
