drm/kms/radeon/agp: Move the check of the aper_size after drm_acp_acquire and drm_agp_info

Browse Source 
First call drm_agp_acquire to check if agp has been acquired.
Second call drm_agp_info to fill in the info data struct, including aper_size.
Finally do the check to see if the aper_size makes sense.
