[libvirt] [PATCH 03/13] nodedev: Need to check for vport capable scsi_host for vHBA searches

When searching for an NPIV capable fc_host, not only does there need to be an "fc_host" capability with the specified wwnn/wwpn or fabric_wwn, but that scsi_host must be vport capable; otherwise, one could end up picking an exising vHBA/NPIV which wouldn't be good. Currently not a problem since scsi_hosts are in an as found forward linked list and the vport capable scsi_hosts will always appear before a vHBA by definition. However, in the near term future a hash table will be used to lookup the devices and that could cause problems for these algorithms.
