block: remove handling of name property

There is no concept of a "NAME" property within libblkid, the value previously
used was the name parameter of blkid_probe_set_uuid_as() which does not denote
the file system name, but the kind of UUID to store.

Since the value never makes sense, stop using it when reporting block
information.
