x86/agp: Fix agp_amd64_init regression
This fixes the regression introduced by commit
42590a75019a50012f25a962246498dead428433 ("x86/agp: Fix
agp_amd64_init and agp_amd64_cleanup").
The above commit changes agp_amd64_init() not to do anything if
gart_iommu_aperture is not zero.
If GART iommu calls agp_amd64_init(), we need to skip
agp_amd64_init() when it's called later via module_init.
The problem is that gart_iommu_init() calls agp_amd64_init()
with not zero gart_iommu_aperture so agp_amd64_init() is never
initialized.
When gart_iommu_init() calls agp_amd64_init(), agp should be
always initialized.
