Bug Description

[Impact]
The implementation of rollover allows transfers to reset the block number counter back to 0 after reaching 2^16, allowing to transfer files of any size. This is particularly useful when grabbing large files. This prevents MAAS from successfully installing windows based OS's.

[Test Case]
1. Install MAAS
2. Upload aa windows image.
3. Deploy windows with traidtional installer.
4. Without the fix, windows will fail to deploy.
5. With the fix, windows will deploy correctly.

[Regression Potential]
Minimal, this has been tested in various different environments and QA'd.
