Use DEFINE_WAIT instead of DECLARE_WAITQUEUE, because we use
prepare/finish_wait since commit
3e3b5c087799e536871c8261b05bc28e4783c8da
(tty: use prepare/finish_wait)
Otherwise we would oops in finish_wait.

That won't compile. DEFINE_WAIT(wait) will though.

Ah, crap. One should teach himself using commit --amend.
