( https://gerrit.ovirt.org/79686 ) Change subject: core: Fix potential NPE when using NetworkPolicyUnit ...................................................................... core: Fix potential NPE when using NetworkPolicyUnit PolicyUnitImpl#filter is only called from one place, SchedulingManager#runInternalFilters, which assumes it cannot return null. NetworkPolicyImpl breaks this rule by returning null if it's pass an empty list of hosts. This patch prevents this potential bug by returning an empty list instead.
