drm/xe/bo: Don't include the CCS metadata in the dma-buf sg-table
commit 449bcd5d45eb4ce26740f11f8601082fe734bed2 upstream.
Some Xe bos are allocated with extra backing-store for the CCS
metadata. It's never been the intention to share the CCS metadata
when exporting such bos as dma-buf. Don't include it in the
dma-buf sg-table.
