replication: Switch to byte-based calls
We are gradually moving away from sector-based interfaces, towards byte-based. Make the change for the last few sector-based calls into the block layer from the replication driver. Ideally, the replication driver should switch to doing everything byte-based, but that's a more invasive change that requires a bit more auditing.
