fix: capture disks when entire peer is offline (#11697)

Browse Source 
currently when one of the peer is down, the
drives from that peer are reported as '0/0'
offline instead we should capture/filter the
drives from the peer and populate it appropriately
such that `mc admin info` displays correct info.
