irda: small read past the end of array in debug code
The "reason" can come from skb->data[] and it hasn't been capped so it
can be from 0-255 instead of just 0-6. For example in irlmp_state_dtr()
the code does:
reason = skb->data[3];
...
irlmp_disconnect_indication(self, reason, skb);
Also LMREASON has a couple other values which don't have entries in the
irlmp_reasons[] array. And 0xff is a valid reason as well which means
"unknown".
So far as I can see we don't actually care about "reason" except for in
the debug code.
