[PATCH v2] staging: android: ion: Initialize dma_address of new sg list

[Liam Mark]

Fix the dup_sg_table function to initialize the dma_address of the new
sg list entries instead of the source dma_address entries.

Since ION duplicates the sg_list this issue does not appear to result in
an actual bug.
