The context for this was before combining mono_delivery_time:1 and
user_delivery_time:1 into tstamp_type:2. No need to add user_delivery_time to
inet_frag_queue because it is combined into tstamp_type:2. If
mono_delivery_time:1 is replaced with tstamp_type:2 in sk_buff, the same should
be done in inet_frag_queue.
