Code Issues Proposed changes

Rename block_device_info_get_root 

The other block_device_info_get_* methods return DriverBlockDevice
objects, but this method returns the root_device_name. We rename it in
preparation for a subsequent patch which adds a method returning a
DriverBlockDevice object for the root disk.
