perf/x86/intel: Fix unintended variable name reuse

commit 1b0dac2ac6debdbf1541e15f2cede03613cf4465 upstream.

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>
