LU-1095 mgs: remove message from console

There is no good reason for a sysadmin to see this message
on the console.  Most of the time this will be a fluke
due to the vagarities of lnet networks (server decides
client is disconnected, but client doesn't know that yet,
messages arriving out of order, etc.).
