When updating the task scan period for NUMA locality checks, update_task_scan_period() checks whether there were no faults or failed migration on the last scan window, at which it prolongs the scan period. However, p->numa_faults_locality, which is used to check for migration failure and number of faults at the previous scan window is not cleared after changing the scan period, which unintentionally increases numa_scan_period up to numa_scan_period_max even when there were no migration failures or no faults at previous scan. Fix this by jumping to the out label on early exit at this case to ensure p->numa_faults_locality is always cleared before returning.
