[PATCH] qemu: Add check for needed paths for memory devices
When building a commandline for a DIMM memory device with
non-default access mode, the qemuBuildMemoryBackendProps() will
tell QEMU to allocate memory from per-domain memory backing dir.
But later, when preparing the host, the
qemuProcessNeedMemoryBackingPath() does not check for memory
devices at all resulting in per-domain memory backing dir not
being created which upsets QEMU.
