Add more functionality to size_changed function. While 'existing' API only detected 0 for unchanged, and !0 for changed, new improved API will also detected if the size has only went bigger - or there was size reduction. Function work for the whole dm-tree - so no change is size is always 0. only size extension 1. and if some size reduction is there - returns -1. This result can be used for better evaluation whether we need to flush before suspend.
