Subject: [PATCH net-next-2.6 1/3] be2net: fix certain cmd failure logging

Some (older)versions of cards/fw may not recognize certain cmds and
return illegal/unsupported errors. As long as the driver can handle
this gracefully there is no need to log an error msg.
Also finetuned 2 existing error log messages.
