Wei Yongjun a454f0ccef xfrm: Fix initialize repl field of struct xfrm_state 
Commit 'xfrm: Move IPsec replay detection functions to a separate file'
  (9fdc4883d9)
introduce repl field to struct xfrm_state, and only initialize it
under SA's netlink create path, the other path, such as pf_key,
ipcomp/ipcomp6 etc, the repl field remaining uninitialize. So if
the SA is created by pf_key, any input packet with SA's encryption
algorithm will cause panic.

    int xfrm_input()
    {
        ...
        x->repl->advance(x, seq);
        ...
    }

This patch fixed it by introduce new function __xfrm_init_state().
