ROSE: AX25: finding routes simplification

With previous patch, rose_get_neigh() routine
investigates the full list of neighbor nodes
until it finds or not an already connected node whether
it is called locally or through a level 3 transit frame.
If no routes are opened through an adjacent connected node
then a classical connect request is attempted.

Then there is no more reason for an extra loop such
as the one removed by this patch.
