[PATCH v5 07/12] hostmem: Rename guest_memfd to guest_memfd_private

[Michael Roth <michael.roth@amd.com>]

From: Peter Xu <peterx@redhat.com>

Rename the HostMemoryBackend.guest_memfd field to reflect what it really
means: whether it needs guest_memfd to back its private guest memory.
This will help avoid conflicts when we introduce supported for using
guest_memfd for shared guest memory via hostmem.
