Shameer Kolothum 77c38c8cf5 iommu: Check return of __iommu_attach_device()
Currently iommu_create_device_direct_mappings() is called
without checking the return of __iommu_attach_device(). This
may result in failures in iommu driver if dev attach returns
error.

Fixes: ce574c27ae27 ("iommu: Move iommu_group_create_direct_mappings() out of iommu_group_add_device()")
