Xin Long 7fe94612dd xfrm: interface: fix the priorities for ipip and ipv6 tunnels 
As Nicolas noticed in his case, when xfrm_interface module is installed
the standard IP tunnels will break in receiving packets.

This is caused by the IP tunnel handlers with a higher priority in xfrm
interface processing incoming packets by xfrm_input(), which would drop
the packets and return 0 instead when anything wrong happens.

Rather than changing xfrm_input(), this patch is to adjust the priority
for the IP tunnel handlers in xfrm interface, so that the packets would
go to xfrmi's later than the others', as the others' would not drop the
packets when the handlers couldn't process them.

Note that IPCOMP also defines its own IPIP tunnel handler and it calls
xfrm_input() as well, so we must make its priority lower than xfrmi's,
which means having xfrmi loaded would still break IPCOMP. We may seek
another way to fix it in xfrm_input() in the future.
