QUIC: removed check for in-flight packets in computing PTO.
The check is needed for clients in order to unblock a server due to
anti-amplification limits, and it seems to make no sense for servers.
See RFC 9002, A.6 and A.8 for a further explanation.
This makes max_ack_delay to now always account, notably including
PATH_CHALLENGE timers as noted in the last paragraph of 9000, 9.4,
unlike when it was only used when there are packets in flight.
While here, fixed nearby style.
