knfsd: use a spinlock to protect sk_info_authunix
sk_info_authunix is not being protected properly so the object that it points to can be cache_put twice, leading to corruption. We borrow svsk->sk_defer_lock to provide the protection. We should probably rename that lock to have a more generic name - later. Thanks to Gabriel for reporting this.
