Re: [PATCH v3 2/8] [RFC] dir: report number of visited directories and paths with trace2

Provide more statistics in trace2 output that include the number of
directories and total paths visited by the directory traversal logic.
Subsequent patches will take advantage of this to ensure we do not
unnecessarily traverse into ignored directories.

And this change is the reason behind how the call to the trace
statistics helper is now outside the "if (untracked)" block after
patch 1/8; makes sense to me.
