ANDROID: staging: ion: use dma_[un]map_sg_attrs

Browse source 
The [un]map_dma_buf receives dma_buf_attachment by
parameter. The caller could set the dma_map_attrs
on dma_buf_attachment such as DMA_ATTR_SKIP_CPU_SYNC,
and expects that attributes are applied.
The dma_[un]map_sg is changed into dma_[un]map_sg_attrs
to send the attributes.
