net: Reorder initialization in ip_route_output to fix gcc warning

Browse Source 
If I build with W=1, for every file that includes <net/route.h>, I get the warning

    include/net/route.h: In function 'ip_route_output':
    include/net/route.h:135:3: warning: initialized field overwritten [-Woverride-init]
    include/net/route.h:135:3: warning: (near initialization for 'fl4') [-Woverride-init]

(This is with "gcc (Debian 4.6.3-1) 4.6.3")

A fix seems pretty trivial: move the initialization of .flowi4_tos
earlier.  As far as I can tell, this has no effect on code generation.
