[libvirt] [PATCH 1/2] iscsi: Adjust error message for findStorageSources backend

[John Ferlan]

The virStorageBackendISCSIFindPoolSources API only needs the 'host' name
in order to discover iSCSI pools, it returns the various device paths.
On input, it's also possible to further restrict a search by providing the
port attribute for the host element and the (undocumented) initiator element.

For example:

$  virsh find-storage-pool-sources-as iscsi
error: Failed to find any iscsi pool sources
error: invalid argument: hostname and device path must be specified for iscsi sources

$ virsh find-storage-pool-sources-as iscsi 192.168.122.1
<sources>
  <source>
    <host name='192.168.122.1' port='3260'/>
    <device path='iqn.2013-12.com.example:iscsi-chap-lclpool'/>
  </source>
</sources>
