tunneling: Refresh IP header pointer after update_header().

We were assuming that the call to update_header() to finalize tunnel
headers wouldn't cause the skb linear data area to be reallocated.
So far this hasn't been a problem but it's not, generally speaking,
a good assumption to make.  Therefore, refetch the pointer to the IP
header instead of carrying it across the call.
