Subject: hurd: Fix PTR_{,DE}MANGLE calls

	* libio/iofopncook.c (_IO_cookie_read, _IO_cookie_write,
	_IO_cookie_seek, _IO_cookie_close, _IO_old_cookie_seek)
	[!PTR_DEMANGLE]: Do not call PTR_DEMANGLE.
	(set_callbacks) [!PTR_MANGLE]: Do not call PTR_MANGLE.
	* libio/vtables.c (_IO_vtable_check)
	[!PTR_DEMANGLE]: Do not call PTR_DEMANGLE.
	* libio/libioP.h (IO_set_accept_foreign_vtables)
	[!PTR_MANGLE]: Do not call PTR_MANGLE.
