drm/radeon/kms: avoid possible oops (call gart_fini before gart_disable)
radeon_gart_fini might call GART unbind callback function which might try to access GART table but if gart_disable is call first the GART table will be unmapped so any access to it will oops. Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
