vhdx: 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 vhdx driver.
Ideally, the vhdx driver should switch to doing everything
byte-based, but that's a more invasive change that requires a
bit more auditing.
