smbd: Adjust debug level of "No protocol supported" message

SMB clients only supporting SMB1 connecting to a Samba server that only
accepts SMB protocol versions 2 and 3 can spam the logs with the "No
protocol supported" message. This is useful information for debugging
failed connection attempts, but it should not be in the default log.
Adjust it to NOTICE/3.
