less than 3, to keep in line with TCP {{?RFC5681}}.

Some networks may exhibit higher degrees of reordering, causing a sender to
detect spurious losses. Implementers MAY use algorithms developed for TCP, such
as TCP-NCR {{?RFC4653}}, to improve QUIC's reordering resilience.
detect spurious losses. Algorithms that increase the reordering threshold after
spuriously detecting losses, such as TCP-NCR {{?RFC4653}}, have proven to be
useful in TCP and are expected to at least as useful in QUIC. Re-ordering
could be more common with QUIC than TCP, because network elements cannot observe
and fix the order of out-of-order packets.
