db: enable metadump on CRC filesystems
Now that we can calculate CRCs through xfs_db, we can add support
for recalculating CRCs on obfuscated metadump images. This simply
requires us to call the write verifier manually before writing the
buffer to the metadump image.
We don't need to do anything special to mdrestore, as the metadata
blocks it reads from the image file will already have all the
correct CRCs in them. Hence it can be mostly oblivious to the fact
that the filesystem it is restoring contains CRCs.
