Subject: [PATCH] handle row.power.power being NULL

fixes this error, since device_port_power.power can be null:
Argument "" isn't numeric in numeric gt (>) at /home/netdisco/perl5/lib/perl5/auto/share/dist/App-Netdisco/views/ajax/device/ports.tt line 251.

currently only seen on cisco sb switches, which do have all other columns filled in
      ip       | port | module | admin |   status   | class  | power
