gpu: ion: Explictly mark DMA allocations as GFP_KERNEL
For legacy reasons, the GFP allocation for dma allocations is currently
marked as 0, which corresponds to atomic allocations. These allocations
should not be marked as atomic since the atomic pool is very small.
Switch to properly using GFP_KERNEL to always allocate from the
correct pool.
