btrfs: simplify eb checksum verification in btrfs_validate_metadata_buffer The verification copies the calculated checksum bytes to a temporary buffer but this is not necessary. We can map the eb header on the first page and use the checksum bytes directly. This saves at least one function call and boundary checks so it could lead to a minor performance improvement.
