The existing code assumed that the configuration of a 'parent' attribute
was correct for the createVport path. As it turns out, that may not be
the case which leads errors during the deleteVport path because the
wwnn/wwpn isn't associated with the parent.
With this change the following is reported:
error: Failed to start pool fc_pool_host3
error: XML error: Parent attribute 'scsi_host4' does not match parent 'scsi_host3' determined for the 'scsi_host16' wwnn/wwpn lookup.
for XML as follows:
<pool type='scsi'>
<name>fc_pool</name>
<source>
<adapter type='fc_host' parent='scsi_host4' wwnn='5001a4aaf3ca174b' wwpn='5001a4a77192b864'/>
</source>
Where 'nodedev-dumpxml scsi_host16' provides:
<device>
<name>scsi_host16</name>
<path>/sys/devices/pci0000:00/0000:00:04.0/0000:10:00.0/host3/vport-3:0-11/host16</path>
<parent>scsi_host3</parent>
<capability type='scsi_host'>
<host>16</host>
<unique_id>13</unique_id>
<capability type='fc_host'>
<wwnn>5001a4aaf3ca174b</wwnn>
<wwpn>5001a4a77192b864</wwpn>
...
The patch also adjusts the description of the storage pool to describe the
restrictions.
