btrfs: scrub, only lookup for csums if we are dealing with a data extent
When scrubbing a stripe, whenever we find an extent we lookup for its checksums in the checksum tree. However we do it even for metadata extents which don't have checksum items stored in the checksum tree, that is only for data extents. So make the lookup for checksums only if we are processing with a data extent.
