--timeout is about network connection timeouts. You aren't using the network so it doesn't apply at all. Even if you were networking an unmounted filesystem is an empty directory as far as rsync is concerned and rsync would treat it that way with no idea that you intended to have something mounted there.
Now, I see at the top of your script you check for the existence of the target directory. If that isn't the root of a filesystem then you are good because you are already checking for that. If it is the root of the filesystem then it will exist either as an empty directory or a mount point and you need to check for those possibilities.
