MINOR: quic: emit CONNECTION_CLOSE on app init error

Emit a CONNECTION_CLOSE if the app layer cannot be properly initialized
on qc_xprt_start. This force the quic-conn to enter the closing state
before being closed.

Without this, quic-conn normal operations continue, despite the
app-layer reported as not initialized. This behavior is undefined, in
particular when handling STREAM frames.
