Don't forget to relock the TTY after uiomove() returns an error.

Peter Holm just discovered this funny bug inside the TTY code: if
uiomove() in ttydisc_write() returns an error, we forget to relock the
TTY before jumping out of ttydisc_write(). Fix it by placing
tty_unlock() and tty_lock() around uiomove().
