Improve cached kernel memory accounting using meminfo KReclaimable field

KReclaimable field from /proc/meminfo is designed to represent total amount
of memory that kernel can reclaim when needed. This includes reclaimable
memory consumed by slab and reported in SReclaimable field as well as ION
pools. By using KReclaimable instead of SReclaimable we will account for
ION pools currently reported under "Lost RAM" category in dumpsys meminfo
report.
