We currently print a DRM_DEBUG_KMS message on the happy path and don't
print anything on the "failed to allocate" path. On some desktop
environments (e.g., Unity) I see the "scheduling delayed FBC enable"

So kill the useless message for the happy case, saving a lot of dmesg
space, and properly signal the "kzalloc fail" case.
