numa: report all DIMM/NVDIMMs as plugged memory

Right now, there is some inconsistency between hotplugged and
coldplugged memory. DIMMs added via "-device" result in different stats
than DIMMs added using "device_add".

E.g.
    [...]
    -numa node,nodeid=0,cpus=0-1 -numa node,nodeid=1,cpus=2-3 \
    -m 4G,maxmem=20G,slots=2 \
    -object memory-backend-ram,id=mem0,size=8G \
    -device pc-dimm,id=dimm0,memdev=mem0 \
    -object memory-backend-ram,id=mem1,size=8G \
    -device nvdimm,id=dimm1,memdev=mem1,node=1

Results in NUMA info
    (qemu) info numa
    info numa
    2 nodes
    node 0 cpus: 0 1
    node 0 size: 10240 MB
    node 0 plugged: 0 MB
    node 1 cpus: 2 3
    node 1 size: 10240 MB
    node 1 plugged: 0 MB

But in memory size summary:
    (qemu) info memory_size_summary
    info memory_size_summary
    base memory: 4294967296
    plugged memory: 17179869184

Make this consistent by reporting all hot and coldplugged
memory a.k.a. DIMM and NVDIMM as "plugged".
