From: Kaitao Cheng <[email protected]> prep_compound_page() calls prep_compound_head(), which initializes folio->_deferred_list for compound folios with an order greater than one. Therefore, dax_folio_init() initializes the list twice for large DAX folios.
Remove the redundant initialization from dax_folio_init(). This leaves the behavior unchanged and keeps compound folio initialization centralized in prep_compound_head().
