Fix incorrect error message in iovctl

Browse Source 
If the iovctl command was invoked with only the -C flag, the user would
receive a message claiming that they needed to also supply either the
-d flag or the -f flag.  However, in the case of the -C mode, only the
-f flag is acceptable.  Correct this error message in this case.
