[PATCH 01/16] befs: Convert befs_symlink_read_folio() to use folio_end_read()

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

This is slightly more efficient than separate calls to
folio_mark_uptodate() and folio_unlock(), and it's easier to read.
Get rid of the call to folio_set_error() as nobody will check this flag.
