iommu/arm-smmu-v3: Fix incorrect return in arm_smmu_attach_dev
After commit 48e7b8e284e5 ("iommu/arm-smmu-v3: Remove
arm_smmu_domain_finalise() during attach"), an error code is not
returned on the attach path when the smmu does not match with the
domain. This causes problems with VFIO because
vfio_iommu_type1_attach_group() relies on this check to determine domain
compatability.
Re-instate the -EINVAL return value when the SMMU doesn't match on the
device attach path.
Fixes: 48e7b8e284e5 ("iommu/arm-smmu-v3: Remove arm_smmu_domain_finalise() during attach")
