PM: sleep: stats: Use locking in dpm_save_failed_dev()
Because dpm_save_failed_dev() may be called simultaneously by multiple
failing device PM functions, the state of the suspend_stats fields
updated by it may become inconsistent.
Prevent that from happening by using a lock in dpm_save_failed_dev().
