NLA types consist of a type and two flags, add new fields for this. Add a new parameter to restrict the data consumed by the dissect_netlink_attributes function, this is needed when implementing nested attributes using another call to this function. This also avoids adding padding to the payload and matches the comment in include/uapi/linux/netlink.h (Linux 4.7).
