    libswan/ttoaddress.c: attempt to fix a crash in ttoaddress_dns
    
    Cagney observed a crash in the version of ttoaddress_dns that uses getaddrinfo.
    It looks as if freeaddrinfo is trying to free something that wasn't malloced.
    The best explanation is that getaddrinfo does NOT set *res if some failure
    is recognized (this is not documented).
    
    This commit initialized res to NULL.  That should work if freeaddrinfo
    does or does not set *res on failure.
