[ 23/63] tracing: Fix off-by-one on allocating stat->pages

[Greg Kroah-Hartman]

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Namhyung Kim <namhyung.kim@xxxxxxx>

commit 39e30cd1537937d3c00ef87e865324e981434e5b upstream.

The first page was allocated separately, so no need to start from 0.
