gpu: nvgpu: Drop version check for DMA BUF namespace

Browse Source 
The MODULE_IMPORT_NS macro adds a namespace tag to the module
information. The DMA_BUF namespace is required for Linux v5.16+ kernels
for drivers that use DMA BUF, there is no reason not to populate this
for earlier kernels. Furthermore, some 3rd party kernels prior to v5.16
may require this too and so drop the version check around the DMA BUF
namespace.

The MODULE_IMPORT_NS macro was introduced in Linux v5.4 and so if the
kernel defines this, then add the DMA_BUF namespace.
