xfs: directory scrubber must walk through data block to offset In xfs_scrub_dir_rec, we must walk through the directory block entries to arrive at the offset given by the hash structure. If we blindly trust the hash address, we can end up midway into a directory entry and stray outside the block. Found by lastbit fuzzing lents[3].address in xfs/390 with KASAN enabled.
