Bug Description
When detaching a volume, Nova doesn't disconnect the iSCSI portal and just return for there are other volumes attaching to the host. But the mutipath mapping device descriptor is there and multipath tool sends IOs periodically to storage array. This leads to some cinder storage drivers, such as huawei, can not unmap that volume for it detect periodic IOs.
So we need to remove the multipath device descriptor in this case.

Remove multipath mapping device descriptor
When detaching a volume from a instance, we need to remove
multipath mapping device descriptor if there are other volumes
mapping to the host instead of do nothing, for some cinder drivers
can not terminate connection for multipath tool sending IOs to
storage array periodically.
