SOF_TIMESTAMPING_OPT_STATS can be enabled and disabled
while packets are collected on the error queue.
So, checking SOF_TIMESTAMPING_OPT_STATS in sk->sk_tsflags
is not enough to safely assume that the skb contains
OPT_STATS data.
Add a bit in sock_exterr_skb to indicate whether the
skb contains opt_stats data.
Fixes: 1c885808e4 ("tcp: SOF_TIMESTAMPING_OPT_STATS option for SO_TIMESTAMPING")
