 'cwe': ['CWE-667'], 'message': 'libxl: Disable death events after receiving a shutdown event

The libxl driver will handle all domain destruction and cleanup
when receiving a domain shutdown event from libxl. Commit fa30ee04a2a
introduced the ignoreDeathEvent boolean in the DomainObjPrivate struct
to ignore subsequent death events from libxl. But libxl already provides
a mechanism to disable death events via libxl_evdisable_domain_death.

This patch partially reverts commit fa30ee04a2a and instead uses
libxl_evdisable_domain_death to disable subsequent death events when
processing a shutdown event.
