x86/agp: Fix agp_amd64_init and agp_amd64_cleanup
This fixes the regression introduced by the commit
f405d2c02395a74d3883bd03ded36457aa3697ad.
The above commit fixes the following issue:
http://marc.info/?l=linux-kernel&m=126192729110083&w=2
However, it doesn't work properly when you remove and insert the
agp_amd64 module again.
agp_amd64_init() and agp_amd64_cleanup should be called only
when gart_iommu is not called earlier (that is, the GART IOMMU
is not enabled). We need to use 'gart_iommu_aperture' to see if
GART IOMMU is enabled or not.
