[libvirt] [PATCH 9/9] virsh: allow empty targets in cmdDomFSInfo

[Ján Tomko]

Ever since the introduction of the guest-get-fsinfo command
in QEMU commit 46d4c572 qga/qapi-schema.json says that
the 'disks' array can possibly be empty. For example when getting
the target list is unsupported:
https://bugzilla.redhat.com/show_bug.cgi?id=1567041

Pass an empty string instead of NULL to vshTableRowAppend to prevent
a mismatched column number.
