[blivet:master] Simple patch for #1172172

[Anne Mulhern]

The alternative is to update LVMLogicalVolumeDevice.updateKSData() so that
it records a size for an existing device.

I think I prefer the alternative I've posted, but it is a little hard to tell
given how long and puzzling LogVolData.execute() is.

  If using pre-existing, no size needs to be specified in ksdata

ACK.
