helper/command: remove dead code in command_unknown() 

Commit 89fa493a3b removes the top
level command "unknown" and adds in command_unknown() some unclear
code that should detect a user-implemented "unknown" command.
But, all the commands that trigger the execution of the function
command_unknown() are registered in register_command_handler() and
have the command name prefixed with "ocd_".
Due to such "ocd_" prefix in cmd_name, the condition
	if (strcmp(cmd_name, "unknown") == 0) { ... }
is always false.
Nobody complained for almost 10 years so we can proceed to remove
this dead code, before merging any change that obsoletes the
prefix "ocd_" and potentially makes the condition true.

Remove the dead code guarded by the condition above.
