Subject: iommu: Don't use sme_active() in generic code
Git-commit: 2896ba40d0becdb72b45f096cad70633abc014f6
Patch-mainline: v5.4-rc1
References: bsc#1151661 bsc#1151700
Switch to the generic function mem_encrypt_active() because
sme_active() is x86 specific and can't be called from
generic code on other platforms than x86.
Fixes: 2cc13bb4f59f ("iommu: Disable passthrough mode when SME is active")
