doc: THP CoW fault no longer allocate THP
Since commit 3917c80280c9 ("thp: change CoW semantics for anon-THP"),
THP CoW page fault is rewritten. Now it just splits pmd then fallback
to base page fault, it doesn't try to allocate THP anymore. So it is no
longer counted in THP_FAULT_ALLOC.
Remove the obsolete statement in documentation about THP CoW allocation
to avoid confusion.
