Better detection of the device (mga#18411), avoiding to write to a partition.
The device is obtained through Drive list of udisks2, but without /dev/sdxx name. This is got trough Block list, but without direct correspondance. Thus, we get the first block which has 'Drive' the selected Drive, and suppress the trailing digits. Clean unused code
