commit 6e79202b metadump: fully support discontiguous directory blocks
assembled a buffer from multiple dir blocks, and we can use that in
obfuscate_dir_data_block() to continue past the first filesystem block
and continue obfuscating the entire thing.
Without this, anything after the first block was skipped, and
remained as cleartext.
