Jon Hunter aa44d0e041 gpu: nvgpu: Fix build for Linux v5.16-rc1 ...

Building NVGPU against the current upstream mainline kernel is failing
and errors such as the following are seen.

ERROR: modpost: module nvgpu uses symbol dma_buf_map_attachment from
	namespace DMA_BUF, but does not import it.
ERROR: modpost: module nvgpu uses symbol dma_buf_detach from namespace
	DMA_BUF, but does not import it.
ERROR: modpost: module nvgpu uses symbol dma_buf_vmap from namespace
	DMA_BUF, but does not import it.

Following upstream commit 16b0314aa746 ("dma-buf: move dma-buf symbols
into the DMA_BUF module namespace"), it is now necessary to import the
DMA_BUF module namespace into the NVGPU driver to fix this.
