[libvirt] [PATCH 09/10] libxl_migration: Resolve Coverity NULL_RETURNS

[John Ferlan]

Coverity noted that all callers to libxlDomainEventQueue() could ensure
the second parameter (event) was true before calling except this case.
As I look at the code and how events are used - it seems that two events
would have been sent which more than likely causes some bad stuff for
the second one.  So just remove one call and let the cleanup: handle
the event.  In the future if there's code between getting the event
and cleanup that needs to send the event, this will have to change in
order to send the event and set event = NULL (although it seems unlikely
to happen).
