ceph-volume: fix lvm list

17957d9 introduced a regression in `lvm
list`.

When passing a vg/lv path for generating a single report, it fails
because the filter used in the `lvs` command isn't right. It uses the lv
name instead of the vg name because `os.path.basename(device)` is used
while it should be `os.path.dirname(device)`
