get rid of fs_value_is_filename_empty
Its behaviour is identical to that of fs_value_is_filename. It makes no sense, anyway - LOOKUP_EMPTY affects nothing whatsoever once the pathname has been imported from userland. And both fs_value_is_filename and fs_value_is_filename_empty carry an already imported pathname. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
