xfrm: Fix truncation length of authentication algorithms installed via PF_KEY
Commit 4447bb33f09444920a8f1d89e1540137429351b6 ("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.
