quic: fix quicly fifo size mismatch

- This fixes an intermittent failure of the
  test_quic_ext_transfer test due to quicly
  being configured with the wrong fifo size
  which was taken from the cli or startup.conf
  file. The fifo size from the application
  context is now used when creating the
  quicly context.
- Emit an error message if the entire chunk
  of a stream is not enqueued in the svm fifo.

Type: fix
