[patch 50/59] IPV4: Fix single-entry /proc/net/fib_trie output.

[Chris Wright <chrisw@sous-sol.org>]

-stable review patch.  If anyone has any objections, please let us know.
------------------

From: Robert Olsson <robert.olsson@its.uu.se>

When main table is just a single leaf this gets printed as belonging to the
local table in /proc/net/fib_trie. A fix is below.
