drm/test: fix the gem shmem test to map the sg table.

The test here creates an sg table, but never maps it, when
we get to drm_gem_shmem_free, the helper tries to unmap and this
causes warnings on some platforms and debug kernels.

This also sets a 64-bit dma mask, as I see an swiotlb warning if I
stick with the default 32-bit one.
