[libvirt] [libvirt-test-API][PATCH] npiv: Add basic NPIV test case

Tue Oct 22 04:28:09 UTC 2013
The original NPIV test function create_virtual_hba doesn't check the
validation of fabric_wwn, this patch modify create_virtual_hba to check
fabric_wwn whether is invalid (0xffffffff).
One the other hand, add a function destroy_virtual_hba to clean the vHBA which
is created by create_virtual_hba.
Add a global variable wwnn to global.cfg for create_virtual_hba. And add the
test case conf file basic_npiv.conf.
