xfrm: Fix truncation length of authentication algorithms installed via PF_KEY

Commit 4447bb33f0 ("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.
