FOLL_SPLIT") and commit ba925fa350 ("s390/gmap: improve THP splitting")
FOLL_SPLIT has not been used anymore. Remove the dead code.

When demonstrating FOLL_SPLIT in transhuge document, migration is used
as an example. But, since commit 94723aafb9 ("mm: unclutter THP
migration"), the way of THP migration is totally changed. FOLL_SPLIT is
not used by migration anymore due to the change.
Remove the obsolete example to avoid confusion.
