[rancid] error in Cisco MDS config retrieval

It has to do with how NX-OS handles features that aren't enabled (and/or
aren't available on that hardware platform).

In 3.1, I went into the nxrancid script and changed the return value for
invalid commands since I have some devices that can use some of the stock
commands and some cannot and I didn't want to create a slew of new device
types.

diff -u nxrancid.orig nxrancid

        next if (/^(\s*|\s*$cmd\s*)$/);
        return(1) if /Line has invalid autocommand /;
        return(1) if /(Invalid input detected|Type help or )/;
-       return(-1) if (/\% Invalid command at /);
+       return(1) if (/\% Invalid command at /);
        return(-1) if (/\% Permission denied/);
        return(-1) if (/command authorization failed/i);

In 3.2, that has moved to the nxos module.

I'm sure there's probably a better way to handle it, but I was feeling
pretty lazy at the time and haven't had a chance to revisit it.
