[PATCH 05/16] hpfs: Convert hpfs_symlink_read_folio to use a folio

["Matthew Wilcox (Oracle)" <willy@infradead.org>]

Remove the conversion back into a page and use the folio APIs throughout.
Remove the setting of PG_error instead of converting it; it is unused
by core code or by the rest of HPFS, so it serves no purpose here.
