PM / Suspend: Avoid code duplication in suspend statistics update

The code
       if (error) {
               suspend_stats.fail++;
               dpm_save_failed_errno(error);
       } else
               suspend_stats.success++;

Appears in the kernel/power/main.c and kernel/power/suspend.c.

This patch just creates a new function to avoid duplicated code.
