nvme: don't create a multipath node for zero capacity devices

Browse source 
Apparently there are nvme controllers around that report namespaces
in the namespace list which have zero capacity.  Return -ENXIO instead
of -ENODEV from nvme_update_ns_info_block so we don't create a hidden
multipath node for these namespaces but entirely ignore them.

Fixes: 46e7422cda ("nvme: move common logic into nvme_update_ns_info")
