Dag Wieers a3667767e6 Fix check-mode incorrectly returning changed (#2220)
The lvol module has a different logic in check-mode for knowing when a change is induced. And this logic is *only* based on a size check. However during a normal run, it is the lvreduce or lvextend tool that decides when a change is performed (or when the requested and existing sizes differ). So while in check-mode the module reports a change, in real run-mode it does not in fact changes anything an reports ok.

One solution would be to implement the exact size-comparison logic that is implemented in lvextend and lvreduce, but we opted to use the `--test` option to each command to verify if a change is induced or not. In effect both check-mode and run-mode use the exact same logic and conclusion.
