Subject[ 090/136 ] perf/x86/intel: Fix unintended variable name reuse
3.6.11.4 stable review patch.
If anyone has any objections, please let me know.

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

From: =?UTF-8?q?Jan-Simon=20M=C3=B6ller?= <dl9pf@gmx.de>

[ Upstream commit 1b0dac2ac6debdbf1541e15f2cede03613cf4465 ]

The variable name events_group is already in used and led to a
compilation error when using clang to build the Linux Kernel .
The fix is just to rename the var. No functional change. Please
apply.

Fix suggested in discussion by PaX Team <pageexec@freemail.hu>
