udf: Fix free space reporting for metadata and virtual partitions

Browse source

[ Upstream commit a4a8b99ec8 ]

Free space on filesystems with metadata or virtual partition maps
currently gets misreported. This is because these partitions are just
remapped onto underlying real partitions from which keep track of free
blocks. Take this remapping into account when counting free blocks as
well.
