mm: swap: memcg: fix memcg stats for huge pages
The commit 2262185c5b28 ("mm: per-cgroup memory reclaim stats") added PGLAZYFREE, PGACTIVATE & PGDEACTIVATE stats for cgroups but missed couple of places and PGLAZYFREE missed huge page handling. Fix that. Also for PGLAZYFREE use the irq-unsafe function to update as the irq is already disabled.
