Unfortunately it looks like gcc 3.3.5 at least is too dumb to optimise
it away.  I think we'll need a better strategy.

OK, the idea is still the same: Move the loop from dst_output into
xfrm4_output/xfrm6_output since they're the only ones who need to it.

In order to avoid the tail call issue, I've added the inline function
nf_hook which is nf_hook_slow plus the empty list check.

Thanks, this looks great. I've changed it to only call the hooks
before tunnel mode transforms and added a missing dst_output call
for the final packet.
