live: hw_inventory: fix empty memory bank bug

When a client's hardware presents an empty memory bank and invalid call
to _bytes_to_human is performed because None is passed as a parameter.

	size = _bytes_to_human(obj.get('size', None))

Fix this by checking if 'size' is present in the JSON output from lshw.
If size is present then map the bytes to a human readable string using
_bytes_to_human, if no size is present then use 'Empty slot' to indicate
that the memory bank is not being used.
