tty: termios locking functions break with new termios type

I ran into a few problems.

n_tty_ioctl() for instance:

drivers/char/tty_ioctl.c:799: error: $,1rxstruct termios$,1ry has no
member named $,1rxc_ispeed$,1ry

This is calling the copy interface that is supposed to be using
a termios2 when the new interfaces are defined, however:

	case TIOCGLCKTRMIOS:
		if (kernel_termios_to_user_termios((struct termios __user *)arg, real_tty->termios_locked))
			return -EFAULT;
		return 0;

This is going to write over the end of the userspace
structure by a few bytes, and wasn't caught by you yet
because the i386 implementation is simply copy_to_user()
which does zero type checking.
