mgr/cephadm: Fix unfound progress events

While applying service specs, cephadm creates a progress event for
the daemons to be added or deleted from the hosts. The progress
event is initialized if progress_total is greater than 0
but at the end cephadm tries to mark the progress event as
complete/fail even though progress event has not been initialized.

Mark progress events as complete/fail only if they are initialized.
