drm/radeon/kms: don't fail if we fail to init GPU acceleration
Userspace can query if acceleration is working or not true get info ioctl and could fallback to software if for some reason kernel failed to initialize KMS. This should allow to give a working KMS setup in all case (even with non functionning accel). Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
