Remove obsolete stateless reset token length override

These two lines are no longer correct. QuicSession calls QuicConfig::SetStatelessResetTokenToSend and then QuicConfig will populate the transport parameters with the right value. This call is currently a no-op as the stateless reset token is always 16 bytes long.

Remove obsolete code
