[Libguestfs] [PATCH] daemon: inspect_fs_windows: Handle parted errors

By creating an empty disk and using it as the first disk of the vm (i.e. /dev/sda, /dev/sdb{1,2} contains the windows fses) we change the iteration order of the disks. This causes inspect_os() to fail since Parted returns a Unix_error if the device does not contain any partitions - fix this by handling this Unix_error.
