BUG/MINOR: quic: Possible skipped RTT sampling

There are very few chances this bug may occur. Furthermore the consequences
are not dramatic: an RTT sampling may be ignored. I guess this may happen
when the now_ms global value wraps.

Do not rely on the time variable value a packet was sent to decide if it
is a newly acknowledged packet but on its presence or not in the tx packet
ebtree.

Must be backported as far as 2.6.
