ext4: add large folios support for moving extents

Browse source

Pass the moving extent length into mext_folio_double_lock() so that it
can acquire a higher-order folio if the length exceeds PAGE_SIZE. This
can speed up extent moving when the extent is larger than one page.
Additionally, remove the unnecessary comments from
mext_folio_double_lock().
