xfrm: Fix initialize repl field of struct xfrm_state
Commit 'xfrm: Move IPsec replay detection functions to a separate file' (9fdc4883d92d20842c5acea77a4a21bb1574b495) 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().
