pf error returns

Hmm. I might be making this harder than it needs to be.
If the netpfil hook returns EACCESS ip_forward() won't actually generate an
ICMP error message.

The problem is that PF returns PF_PASS, PF_DROP, ... instead of the error codes
the stack expects.

Can you test this patch?

It's interesting that this doesn't seem to be as big a problem on CURRENT,
because the fast forwarding code (ip_tryforward()) doesn't generate ICMP errors
for netpfil() errors.
