[libvirt] [PATCH 01/11] nodedev: Fix crash in libvirtd on vHBA creation path

Providing XML such as: <device> <name>vhba</name> <capability type='scsi_host'> <capability type='fc_host'> </capability> </capability> </device> would crash libvirt because the '<parent>' isn't a required field, but for vHBA creation it's expected (day 1 issue - see commit id '81d0ffbc'). The nodedev.rng added in commit id '2c22a68c' has this as an optional field. NB: On normal udev discovery if a parent field wasn't found, it would be set to "computer" by udevSetParent, so this is a somewhat unique path.
