Docs/admin-guide/cgroup-v2: fix memory.stat doc details

Browse Source 
Fix minor cgroup v2 memory.stat documentation issues.  Correct the
vmalloc per-node marker now that vmalloc uses the native NR_VMALLOC node
stat, and document zswap_incomp as a byte-valued memory amount instead
of as a page counter.

Fixes: c466412c73 ("mm: memcontrol: switch to native NR_VMALLOC vmstat counter")
Fixes: 5ad41a38c3 ("mm: zswap: add per-memcg stat for incompressible pages")
