src/rrd_list.c: fix local directory listing when connection to rrdcached fails

        Without this fix, when the remote rrdcached cannot be reached
        and a path that exists on the local machine (such as '/') is
        asked for,  'list' returns 'ls' of the local path.

        Example of erroneous output:

	$ rrdtool list -d rrdcached-host:42222 /
