ipv6: sr: restruct ifdefines
There are too many ifdef in IPv6 segment routing code that may cause logic
problems. like commit 160e9d275218 ("ipv6: sr: fix invalid unregister error
path"). To avoid this, the init functions are redefined for both cases. The
code could be more clear after all fidefs are removed.
