CSI: handle per-alloc volumes in alloc status -verbose CLI (#12573)

The Nomad client's `csi_hook` interpolates the alloc suffix with the
volume request's name for CSI volumes with `per_alloc = true`, turning
`example` into `example[1]`. We need to do this same behavior in the
`alloc status` output so that we show the correct volume.
