dynamic_debug: simplify dynamic_debug_init error exit
We dont want errors while parsing ddebug_query to unload ddebug
tables, so set success after tables are loaded, and return 0 after
query parsing is done.
Simplify error handling code since its no longer used for success,
and change goto label to out_err to clarify this.
