gpu: nvgpu: fix per-GPU DMA allocation tracking
- total DMA memory allocation is currently tracked by adding page aligned
size of nvgpu_mem
- The sequence is roughly as follows:
- total dma memory used += mem->aligned_size
- mem->aligned_size = PAGE_ALIGN(size)
- In above sequence, nvgpu_mem structure is initially zero when it is added
to total dma memory used after which it is assigned page aligned value
- This patch fixes total dma memory usage tracking.
