[roll] Roll fuchsia [fxfs][fsck] Fix spurious fsck error

Running fsck on a filesystem with an empty volume was erroneously
failing.  The allocator reports (correctly) that 0 bytes are allocated
to the volume, but Fsck fails to filter this out and complains that the
owner_allocated_bytes is different than what is observed.
