LU-14114 lnet: print device status in net show command

A device can be in fatal state, if the cable was disconnected, or the
port brought down on the switch side. In these cases, the LND (o2iblnd
for now), will flag the device in fatal state. That device will not be
used any further. However, it's health will not be decremented. This
causes some confusion when examining the state of the node.
It is better to print the device status in the output of the lnetctl
net show command.
