irda: Add irda_skb_cb qdisc related padding

commit 69c30e1e7492192f882a3fc11888b320fde5206a upstream.

We need to pad irda_skb_cb in order to keep it safe accross dev_queue_xmit()
calls. This is some ugly and temporary hack triggered by recent qisc code
changes.
Even though it fixes bugzilla.kernel.org bug #11795, it will be replaced by a
proper fix before 2.6.29 is released.
