tests: (lvm_setup.yml), don't shrink lvol 

when rerunning lvm_setup.yml on existing cluster with OSDs already
deployed, it fails like following:

```
fatal: [osd0]: FAILED! => changed=false
  msg: Sorry, no shrinking of data-lv2 to 0 permitted.
```

because we are asking `lvol` module to create a volume on an empty VG
with size extents = `100%FREE`.

The default behavior of `lvol` is to shrink the volume if the LV's current
size is greater than the requested size.

Given the requested size is calculated like this:

`size_requested = size_percent * this_vg['free'] / 100`

in our case, it is similar to:

`size_requested = 100 * 0 / 100` which basically means `0`

So the current LV size is well greater than the requested size which
leads the module to attempt to shrink it to 0 which isn't obviously now
allowed.

Adding `shrink: false` to the module calls fixes this issue.
