iommu: No need to set dmar_disabled in check_zero_address()
Before the restructruing of the x86 IOMMU code, intel_iommu_init() was getting called directly from pci_iommu_init() and hence needed to explicitly set dmar_disabled to 1 for the failure conditions of check_zero_address(). Recent changes don't call intel_iommu_init() if the intel iommu detection fails as a result of failure in check_zero_address(). So no need for this ifdef and the code inside it.
