Florian Westphal 1de7083006 xfrm: remove output2 indirection from xfrm_mode
similar to previous patch: no external module dependencies,
so we can avoid the indirection by placing this in the core.

This change removes the last indirection from xfrm_mode and the
xfrm4|6_mode_{beet,tunnel}.c modules contain (almost) no code anymore.

    172      24       0     196      c4 net/ipv6/xfrm6_mode_tunnel.o

v2: fold the *encap_add functions into xfrm*_prepare_output
    preserve (move) output2 comment (Sabrina)
    use x->outer_mode->encap, not inner
    fix a build breakage on ppc (kbuild robot)
