xfrm: Fix truncation length of authentication algorithms installed vi…

…a PF_KEY Commit 4447bb3 ("xfrm: Store aalg in xfrm_state with a user specified truncation length") breaks installation of authentication algorithms via PF_KEY, as the state specific truncation length is not installed with the algorithms default truncation length. This patch initializes state properly to the default if installed via PF_KEY. Signed-off-by: Martin Willi <[email protected]> Acked-by: Herbert Xu <[email protected]> Signed-off-by: David S.
