QUIC - undo the chromium specific changes from the following CL which
did "Moving work from the QuicSession constructor to
InitializeSession()".

  Merge internal change: 70661792

This CL fixes the crash bug in
net::QuicSession::IsCryptoHandshakeConfirmed. We are accessing
crypto_stream_ before it was created. This could be triggered if the
computer is slow or goes to sleep and crypto handshake not completed
timer goes off.
