When after device removal we handle block pointers remap, skip blocks that might be cloned. BRTs are indexed by vdev id and offset from block pointer's DVA[0]. So if we start addressing the same block by some different DVA, we won't get the proper reference counter. As result, we might either remap the block twice, that may result in assertion during indirect mapping condense, or free it prematurely, that may result in data overwrite, or free it twice, that may result in assertion in spacemap code.
