[libvirt] [PATCH 15/15] tests: Add createVHBAByNodeDevice-parent-fabric-wwn to fchosttest

[John Ferlan]

Add a test that allows providing the parent fabric_wwn in the input XML
in order to create the vHBA.

This also fixes a mixed setting of the fabric_wwn field from the read
test driver XML strings.
