Fix lvresize for thin pool
When resizing thin pool - we need to use strip info from _tdata volume.
In future more generic solution will be necessary once we start to support
lvconvert (resize of stacked devices and stay properly aligned).
For now we just allow striped or linear LV so this code will work.
