virNodeDeviceCapStorageDefFormat: Extract formatting of block size data

Browse Source 
Unfortunately the XML is designed in a weird way, where based on whether
media in the device is removable the sizing is either part of a
subelement or placed directly on top level. The logic itself is
identical so it can be extracted into a function to simplify the
formatter.
