storage: Force setting of disk format type

Commit id '832a9256' adjusted the code to recognize when the default
type of "unknown" was provided as the format type and to use "dos" if
found. Since the pool is built with "dos" and it could cause some
confusion when formatting the XML after building by seeing "unknown"
in the output, let's just adjust the pool's setting to "dos" so that
subsequent formats will see the value.
