Keiichi KII 69c3683ca7 netconsole: avoid null pointer dereference at show_local_mac() ...

This patch avoids a null pointer dereference when we read local_mac 
for netconsole in configfs and shows default local mac address
value.

A null pointer dereference occurs when we call show_local_mac() via 
local_mac entry in configfs before we setup the content of netpoll
using netpoll_setup().
