iommu: Replace __iommu_group_dma_first_attach() with set_domain

Browse source

Reorganize the attach_deferred logic to set dev->iommu->attach_deferred
immediately during probe and then have __iommu_device_set_domain() check
it and not attach the default_domain.

This is to prepare for removing the group->domain set from
iommu_group_alloc_default_domain() by calling __iommu_group_set_domain()
to set the group->domain.
