Subject: [PATCH] perf pmu-events: Removed unused variable

From: Bo Yu <tsu.yubo@...il.com>

Compiling kernel when W=1, it will throw a warning:

pmu-events/jevents.c: In function ‘save_arch_std_events’:
pmu-events/jevents.c:417:15: warning: unused variable ‘sb’ [-Wunused-variable]
  struct stat *sb = data;

Removed the unused variable
