    sbin/hammer: Fix conditional for Hammer_FSId initialization
    Hammer_FSId is initialized when no entry in the VolList yet,
    but this becomes an issue when a new volume (that hasn't joined
    the HAMMER filesystem yet) is the first created volume_info.
    If the second volume_info is for the existing HAMMER volume,
    it is likely that
    bcmp(&Hammer_FSId, &ondisk->vol_fsid, sizeof(Hammer_FSId))
    does not match and results in the following error.
    "load_volume: %s: FSId does match other volumes!"
    The only reason this hasn't become an issue so far is because
    no existing hammer command creates volume_info in that order.
