[SCSI] ses: fix hotplug with multiple devices and expanders
In a situation either with expanders or with multiple enclosure devices, hot add doesn't always work. This is because we try to find a single enclosure device attached to the host. Fix this by looping over all enclosure devices attached to the host and also by making the find loop recognise that the enclosure devices may be expander remote (i.e. not parented by the host).
