iommu: Move the iommu driver sysfs setup into iommu_init/deinit_device()

Browse source

It makes logical sense that once the driver is attached to the device the
sysfs links appear, even if we haven't fully created the group_device or
attached the device to a domain.

Fix the missing error handling on sysfs creation since
iommu_init_device() can trivially handle this.
