pc-dimm: factor out capacity and slot checks into MemoryDevice

Browse source 
Move the checks into memory_device_get_free_addr(). This will check
before doing any calculations if we have KVM/vhost slots left and if
the total region size would be exceeded.

Of course, while at it, make it independent of pc-dimm code.
