Tom Lendacky 4b428e9998 KVM: x86: Fix device passthrough when SME is active 
commit daaf216c06 upstream.

When using device passthrough with SME active, the MMIO range that is
mapped for the device should not be mapped encrypted.  Add a check in
set_spte() to insure that a page is not mapped encrypted if that page
is a device MMIO page as indicated by kvm_is_mmio_pfn().
