BUG/MINOR: quic: ACK_REQUIRED and ACK_RECEIVED flag collision

This packet number space flags were defined with the same value because
defined at different places in the file. Assemble them at the same location
with different values.

This bug could unvalidate the peer address after it was validated
during the handshake leading to the anti-amplication limit to be
enabled again after having been disabled. The situation could not
be unblocked (deadlock).
