mm/khugepaged: change collapse_pte_mapped_thp() to return void
The only external caller of collapse_pte_mapped_thp() is uprobe, which
ignores the return value. Change the external API to return void to
simplify the interface.
Introduce try_collapse_pte_mapped_thp() for internal use that preserves
the return value. This prepares for future patch that will convert the
return type to use enum scan_result.
