[PATCH 20/20] netconsole: suppress log message when opening console file

[Ahmad Fatoum]

As is already being done for the framebuffer console, suppress log
messages when the device is briefly opened via echo.

Otherwise, a netconsole not activated for a CONSOLE_STD* stream,
would each time result in a log message.

We do not replay the dmesg, because if the output path works, the remote
side should be able to input a dmesg command.

This is unlike fbconsole, which has no input.
