The nodeAffinity for portable OSDs is needed to ensure the OSDs are
tied to the same zone or other failure domain where the OSD was
prepared and where it is expected to run. During upgrade the topology
affinity was not being detected since the osd prepare job is skipped
in that case. Now the topology will be detected from the running
OSD daemon pod's node.
