compositor-drm: Check that that we have a valid bo for scanout
If gbm_bo_import does not return a valid buffer for usage of
GBM_BO_USE_SCANOUT don't try and scan out the surface directly.
We've caught the SHM case explicitly earlier - this is to prevent other cases
where the bo cannot be scanned out.
