AOSP: e2fsdroid: Properly free the dedup block map.
When BaseFS specifies the same block for two files, it gets added to a
separate "dedup" bitmap, and removed from the free block bitmap. If the
new build does not use every block in this bitmap, there will be an
inconsistency: the block bitmap marks blocks as in-use when they are
actually free. Although this doesn't matter for AOSP's read-only file
systems, it does cause e2fsck to complain, which breaks the build.
Fix the inconsistency by properly freeing all unused blocks within the
dedup block set.
