[2.6 patch] fix net/ipv4/route.c with gcc 3.4

[Adrian Bunk <bunk@stusta.de>]

The following compile error comes from Linus' tree with 
CONFIG_IP_ROUTE_MULTIPATH_CACHED=y:

<--  snip  -->

...
  CC      net/ipv4/route.o
net/ipv4/route.c: In function `rt_remove_balanced_route':
net/ipv4/route.c:151: sorry, unimplemented: inlining failed in call to 'compare_keys': function body not available
net/ipv4/route.c:540: sorry, unimplemented: called from here
make[2]: *** [net/ipv4/route.o] Error 1

<--  snip  -->


This patch fixes this compile error by moving compare_keys up.
