Fernando Ferraz d1f105a6ed NFS driver: Fix fail creating volume with multiple snapshots

The NFS driver uses qcow2 images with backing files to represent
volume snapshots, which is not allowed for qcow2 disk images
downloaded from glance.  The driver uses cinder.image_utils to
convert a qcow2 snapshot to a raw volume; this was not a problem
for the first snapshot, whose backing file is raw, and hence passed
the image format inspector, but the second snapshot has a qcow2
backing file, which the image_utils were rejecting as a security
risk.  Thus we now pass the qemu_img_info from the backing image as
an additional parameter to the image convert call, which indicates
that the file has already been screened and allows the conversion
to occur.
