Suren Baghdasaryan 5860e852f8 lmkd: remove unused LMK_STAT_STATE_CHANGED notification 
The LmkStateChanged atom was historically used to mark lmk activity
and trigger additional stats polling. For more than a year this has
not been used at all (as statsd supported event-based triggering).
Remove unnecessary functionality.

Kameron Lutes 556740ef04 lmkd: Send Actual OOM Score to lmkd_free_memory_before_kill_hook 
Previously the min_oom score of the candidate search was sent to
lmkd_free_memory_before_kill_hook. This is incorrect as the hook expects
the actual oom score of the process.

Suren Baghdasaryan 0431b65e6c lmkd: prevent the main thread from reaping synchronously 
lmkd main thread is running at RT priority to prevent it from being
blocked by other processes. However when all reaper threads are busy,
lmkd will kill and reap the memory of the target process from the
context of the main thread and that can cause two issues:
1. lmkd main thread gets blocked for considerable duration.
2. lmkd main and reaper threads might monopolize CPUs.
To prevent these issues, when all reaper threads are busy, lmkd will
send a SIGKILL but will not synchronously reap the memory of the target
process.
