KVM: guest_memfd: Use kvm_mem_is_private() when populating guest_memfd memory
Use kvm_mem_is_private() when populating guest_memfd instead of using an
open coded equivalent. In addition to simplifying the populate code *now*,
this avoids the need to provide a range-based gmem lookup API in the future
as well.
No functional change intended.
