[patch 6/9] X.25: Stop /proc/net/x25/route infinitely reading

[akpm@xxxxxxxx]

From: Andrew Hendry <ahendry@xxxxxxxxxxx>

route add --x25 0/0 eth0
cat /proc/net/x25/route
reads the single routing entry forever.

This patch makes x25_get_route_idx behave the same as x25_get_socket_idx
which works correctly.
