drm/radeon/kms: don't call suspend path before cleaning up GPU
In suspend path we unmap the GART table while in cleaning up
path we will unbind buffer and thus try to write to unmapped
GART leading to oops. In order to avoid this we don't call the
suspend path in cleanup path. Cleanup path is clever enough
to desactive GPU like the suspend path is doing, thus this was
redondant.
Tested on: RV370, R420, RV515, RV570, RV610, RV770 (all PCIE)
