QUIC: path revalidation after expansion failure.
As per RFC 9000, Section 8.2.1:
When an endpoint is unable to expand the datagram size to 1200 bytes due
to the anti-amplification limit, the path MTU will not be validated.
To ensure that the path MTU is large enough, the endpoint MUST perform a
second path validation by sending a PATH_CHALLENGE frame in a datagram of
at least 1200 bytes.
