btrfsic_test_for_metadata() directly calls the crc32c() library function for calculating the CRC32C checksum, but then uses btrfs_csum_final() to invert the result. To ease further refactoring and development around checksumming in BTRFS convert to calling btrfs_csum_data(), which is a wrapper around crc32c().
