scheduling: Fix AREM logic for host affinity
This patch updates the AREM algorithms with regards to host affinity.
We sadly have a logic bug in the previously merged version.
All affinity groups have to be considered separately when a VM is part
of multiple host affinity groups. The correct operation for selecting
a valid host is intersection, not union.
