Pradipta Kr. Banerjee 119b6dfc40 storage_conf: Fix libvirtd crash when defining scsi storage pool 
Since 9f781da69d

Resolve a libvirtd crash in virStoragePoolSourceFindDuplicate()
when there is an existing SCSI pool defined with adapter type as
'scsi_host' and defining a new SCSI pool with adapter type as
'fc_host' and parent attribute missing or vice versa.

For example, if there is an existing SCSI pool with adapter type
as 'scsi_host' defined using the following XML

<pool type='scsi'>
  <name>TEST_SCSI_POOL</name>
    <source>
       <adapter type='scsi_host' name='scsi_host1'/>
    </source>
    <target>
        <path>/dev/disk/by-path</path>
    </target>
</pool>

When defining another SCSI pool with adapter type as 'fc_host' using the
following XML will crash libvirtd

<pool type='scsi'>
  <name>TEST_SCSI_FC_POOL</name>
  <source>
     <adapter type='fc_host' wwnn='1234567890abcdef' wwpn='abcdef1234567890'/>
  </source>
  <target>
     <path>/dev/disk/by-path</path>
  </target>
</pool>

Same is true for the reverse case as well where there exists a SCSI pool
with adapter type as 'fc_host' and another SCSI pool is defined with
adapter type as 'scsi_host'.

This happens because for fc_host 'name' is optional attribute whereas for
scsi_host its mandatory. However the check in libvirt for finding duplicate
storage pools didn't take that into account while comparing

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
