Vipin found this issue during a code 'port' from nova to oslo.vmware in review 114551:
https://review.openstack.org/#/c/114551/14/oslo/vmware/selector.py,unified

Quote from vipin:

"I think there is a problem here.

Assume that cluster_mor is None and host_mor is h1. If a datastore d1 is
attached to hosts h1 and h2 where it is accessible only to h2 and not
h1, summary.accessible will be True even though it is not accessible to
h1.

We should use HostMountInfo.accessible in this case."
