Patch for oops in ctc

[Pete Zaitcev <zaitcev@xxxxxxxxxx>]

Martin & others:

the following bug is still with us. What's the deal?
The matter is clear, calling dst_link_failure from an
interrupt is illegal (and pointless).

I have a separate patch which adds carrier control to ctc
according to DaveM's suggestions, but let's at least fix
the bug first.
