[PATCH RFC v5 52/53] KVM: selftests: Update pre-fault test to work with per-guest_memfd attributes

[Ackerley Tng via B4 Relay]

From: Sean Christopherson <seanjc@xxxxxxxxxx>

Skip setting memory to private in the pre-fault memory test when using
per-gmem memory attributes, as memory is initialized to private by default
for guest_memfd, and using vm_mem_set_private() on a guest_memfd instance
requires creating guest_memfd with GUEST_MEMFD_FLAG_MMAP (which is totally
doable, but would need to be conditional and is ultimately unnecessary).
