[PATCH v3 7/7] mm: Documentation: clarify where the mTHP stats live

["Nico Pache (Red Hat)" <nico.pache@linux.dev>]

The note about khugepaged counters references /proc/vmstat for the PMD
case, but never mentions where the mTHPs stats can be found
(i.e.: /sys/kernel/mm/transparent_hugepage/hugepages-<size>kB/stats/)
Add a small addition to this section for clarity.

Also fix a missing period while we are at it.
