staging: android: ion: Fix dma direction for dma_sync_sg_for_cpu/device
commit d6b246bb7a29703f53aa4c050b8b3205d749caee upstream.
Use the direction argument passed into begin_cpu_access
and end_cpu_access when calling the dma_sync_sg_for_cpu/device.
The actual cache primitive called depends on the direction
passed in.
