KMountPoint::List::findByPath() calls realpath for each given path.
When using NetworkManager controlled connections on resume these calls
are blocked, because the connection is not ready at this state.
The function returns from the blocking state after a very long timeout (several minutes) . 
    
This patch avoids blocking realpath calls for pathes directly located in
/etc/mtab. As far as I can see there is no need to call realpath for this cases.
