dma-debug: fix physical address retrieval in debug_dma_sync_sg_for_device

In debug_dma_sync_sg_for_device(), when iterating over a scatterlist,
the debug entry population mistakenly uses the head of the scatterlist
'sg' to fetch the physical address via sg_phys(), instead of using the
current iterator variable 's'.

This causes dma-debug to track the physical address of the very first
scatterlist entry for all subsequent entries in the list.

Fix this by passing the correct loop iterator 's' to sg_phys()
