iommu: Don't use sme_active() in generic code
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") Signed-off-by: Joerg Roedel <jroedel@suse.de>
