[PATCH topic/core-for-CI] Revert "vmstat: disable vmstat_work on vmstat_cpu_down_prep()"

[Lucas De Marchi]

This reverts commit adcfb264c3ed51fbbf5068ddf10d309a63683868.

It completely tanks the CI and nothing gets tested. This is being either
reverted upstream or the fix will conflict with the revert and we will
find out when it does.
