The implementation of i915_drm_buffer_get_handle now handles DRM_API_HANDLE_TYPE_FD in the same way that intel_winsys_import_handle does, by calling drm_intel_bo_gem_create_from_prime.
Tested by successfully running Chrome's ozone_demo [1] with the ozone-gbm backend on an Intel Pineview M machine. Without this change it fails while trying to create a DMA-BUF.
