Subject: [PATCH] nvme: count all ANA groups for ANA Log page
Git-commit: be1277f5eb17a2e5788139eabb0b53dd04c695f3
Patch-mainline: v4.19-rc5
References: bsc#1104967,FATE#325924

When issuing a short read on the ANA log page the number of groups
should not change, even though the final returned data might contain
less groups than that number.
