[PATCH] fix build problem with IPV6

[Stephen Hemminger <shemminger@xxxxxxxx>]

IPV6 won't build in current 2.6.0-test3 tree unless CONFIG_XFRM is defined
because of reference to xfrm6_fini.

The linux way to fix this would be to make the functions
stub's in the include file, but that isn't how IPV6 does it now
for other xfrm functions.
