[PATCH 12/15] drm/virtio: Test for imported buffers with drm_gem_is_imported()

[Thomas Zimmermann]

Instead of testing import_attach for imported GEM buffers, invoke
drm_gem_is_imported() to do the test. The helper tests the dma_buf
itself while import_attach is just an artifact of the import. Prepares
to make import_attach optional.
