iommu: Do iommu_group_create_direct_mappings() before attach
The iommu_probe_device() path calls iommu_create_device_direct_mappings()
after attaching the device.
IOMMU_RESV_DIRECT maps need to be continually in place, so if a hotplugged
device has new ranges the should have been mapped into the default domain
before it is attached.
Move the iommu_create_device_direct_mappings() call up.
