Thanks Uri;) I couldn't explain it better.

Ack.
Although Arnon explained it above, I'd like to clarify (please correct
me if I'm wrong).
This case only happens on system startup.
On system startup, there is a default "startup" session, that is later
replaced with another session. Sometimes the switch between those
sessions are "too fast" such that the first session is terminated before
connecting to the service.
In such a case the service had exited.
When the next session starts we get an event and can retry.
This fix makes vdservice wait for the next session to start, instead of
exiting.
Service exits only if a user is already logged-in (active state).

For cleanliness, I'd add setting _vdi_port to NULL in init_vdi_port()
upon failure.
