Currently, the test is racy and seems to not pass anymore.
In order to rectify it, aim on TCP_TW_RST.

a reasonable compromise for the test. There is a plan in-line comment on

Following change will rename 'monitor_on' DAMON debugfs file to
'monitor_on_DEPRECATED', to make the deprecation unignorable in runtime.
