domainEventRegisterAny called too often

Changeid I090765802bfe443440f16722bc7c43b6280fe56a fixes
bug #1240905 but introduced a bug whereby domainEventRegisterAny
is called on every call to _get_connection.

Conflicts:
        nova/virt/libvirt/driver.py

NOTE(mriedem): The conflict is due to the set_host_enabled
code not being in stable/havana and we don't want to backport
that for the threading fixes in this series.
