commit: Set commit_top_bs->total_sectors
Like in the mirror filter driver, we also need to set the image size for the commit filter driver. This is less likely to be a problem in practice than for the mirror because we're not at the active layer here, but attaching new parents to a node in the middle of the chain is possible, so the size needs to be correct anyway.
