Martin Schwenke ddfbd74607 ctdb-doc: Fix example NFS Ganesha recovery directory maintenance logic
This currently fails exactly when it is needed: when there is a
dangling link pointing into an unmounted filesystem.  This happens
because [ -e <dangling-link> ] returns false.  The solution is simply
to remove that check.

Now the first condition in the "if" statement catches the backward
compatibility case where $GANRECDIR used to be a directory.  It will
also catch other problems, such as if a file has been created in this
location.  If nothing exists then it will silently succeed (due to
-f).

The second case catches a symlink pointing to the wrong place (e.g. in
an unmounted filesystem).
