Suren Baghdasaryan e16047516d lmkd: Add current and max thrashing levels in LMK_MEMORY_STATS reports 
Thrashing threshold tuning requires collecting thrashing level data from
the field and correlating these levels with other indications of device
being non-responsive.
Include current and max thrashing levels in the lmkd kill reports. Max
thrashing level captures the highest level seen since the last kill report.
