Subject: dmidecode: Skip details of uninstalled memory modules
Git-commit: d64af9778d795c7318653f5bc3016295bf67d700
Patch-mainline: yes
References: bsc#1174257

If a memory slot is empty then by definition the fields containing
the memory module details are irrelevant. Best case they are filled
with "Unused" and "None", but in some cases they are even invalid
because the manufacturer did not bother setting the fields to
valid neutral values. So it is better to not print these fields
at all, so as to not confuse the user.
