staging: android: ion: Fix dma direction for dma_sync_sg_for_cpu/device

Browse Source 
commit d6b246bb7a 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.
