Do not use struct drm_gem_object.import_attach unnecessarily. The
field is set by the PRIME import helpers. GEM and other helpers use
it for testing for imported dma-bufs and retrieving the respective
dma-buf instance.
Replace all tests for import_attach with the new GEM helper function
drm_gem_is_imported(). The helper avoids import_attach in favor of
testing the imported dma-buf's object against the provided GEM object.
Also replace references to import_attach.dmabuf. The imported dma-buf
is also available in the GEM object's dma_buf field.
This series cleans up the GEM core and helpers. Drivers also use
import_attach and should later be updated as well.
There's a TODO item for making import_attach entirely optional. This
series is a first step towards this goal.
