The verbose/debug logging done by `cat $DBGFS/dynamic_debug/control`
is voluminous, and clutters logging done during parsing of queries,
which is much more useful when manipulating/enabling callsites.
So increase the required verbosity to 8&9 for per-page and per-line
logging; ie ddebug_proc_(start|stop) and ddebug_proc_(show|next)
respectively. This leaves 2-7 for any further logging tweaks to the
query parsing process.
