Update test_invalid_memory_region_flags() to treat KVM_MEM_NON_COHERENT_DMA
as a supported memslot flag.

Add param "slot" to op get_mt_mask in kvm_x86_ops.
This is a preparation patch to later honor guest PATs for certain memslots.
No functional change intended.

flag KVM_MEM_NON_COHERENT_DMA is not allowed to be
dynamically modified for a memslot.
A KVM_CAP_USER_CONFIGURE_NONCOHERENT_DMA is added to let user space know if
this new memslot flag is supported in KVM.
