drm/vmwgfx: Fix prime with external buffers
Make sure that for external buffers mapping goes through the dma_buf
interface instead of trying to access pages directly.
External buffers might not provide direct access to readable/writable
pages so to make sure the bo's created from external dma_bufs can be
read dma_buf interface has to be used.
Fixes crashes in IGT's kms_prime with vgem. Regular desktop usage won't
trigger this due to the fact that virtual machines will not have
multiple GPUs but it enables better test coverage in IGT.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
