xfrm: remove output indirection from xfrm_mode
Same is input indirection. Only exception: we need to export
xfrm_outer_mode_output for pktgen.
Increases size of vmlinux by about 163 byte:
Before:
text data bss dec filename
15730208 6936948 4046908 26714064 vmlinux
After:
15730311 6937008 4046908 26714227 vmlinux
xfrm_inner_extract_output has no more external callers, make it static.
v2: add IS_ENABLED(IPV6) guard in xfrm6_prepare_output
add two missing breaks in xfrm_outer_mode_output (Sabrina Dubroca)
add WARN_ON_ONCE for 'call AF_INET6 related output function, but
CONFIG_IPV6=n' case.
make xfrm_inner_extract_output static
