Revert "mm: make alloc_demote_folio externally invokable for migration"
This reverts commit a00ce85af2a1be494d3b0c9457e8e81cdcce2a89.
Commit a00ce85af2a1 ("mm: make alloc_demote_folio externally invokable for
migration") was made to let DAMOS_MIGRATE_{HOT,COLD} call the function.
But a previous commit made DAMOS_MIGRATE_{HOT,COLD} call
alloc_migration_target() instead. Hence there are no more callers of the
function outside of vmscan.c. Revert the commit to make the function
static again.
