mm/damon/api: remove unused NR_DAMOS_* enumerators
Patch series "mm/damon/core: cleanup code, reduce stack usage, and add
kunit".
Three various improvements. Patch 1 from Zenghui Yu (Huawei) cleans up
unused enums. Patch 2 from Arnd Bergmann reduces kdamond's stack usage.
Patch 3 from Karl Mehltretter adds a kunit test for uninitialized PSI
quota goal stage logic.
This patch (of 3):
NR_DAMOS_ACTIONS, NR_DAMOS_QUOTA_GOAL_METRICS, and NR_DAMOS_WMARK_METRICS
are not referenced by any code. Remove them.
They can be reintroduced if a real user comes up.
