[f2fs-dev] [PATCH] f2fs: fix to call clear_page_private_reference in .{release, invalid}_folio

[Chao Yu]

b763f3bedc2d ("f2fs: restructure f2fs page.private layout") missed
to call clear_page_private_reference() in .{release,invalid}_folio,
fix it, though it's not a big deal since folio_detach_private() was
called to clear all privae info and reference count in the page.

BTW, remove page_private_reference() definition as it never be used.
