timer_stats_account_timer() reads timer->start_site, then checks it for NULL and then re-reads it again, while timer_stats_timer_clear_start_info() can concurrently reset timer->start_site to NULL. This should not lead to crashes, but can double number of entries in timer stats as start_site is used during comparison, the doubled entries will have unuseful NULL start_site. Read timer->start_site only once in timer_stats_account_timer(). The data race was found with KernelThreadSanitizer (KTSAN).
