[PATCH] [IPV4]: Fix compiler error with CONFIG_PROC_FS=n

[Johann Felix Soden <johfel@gmx.de>]

From: Johann Felix Soden <johfel@users.sourceforge.net>

Handle CONFIG_PROC_FS=n in net/ipv4/fib_frontend.c because:

net/ipv4/fib_frontend.c: In function 'fib_net_init':
net/ipv4/fib_frontend.c:1032: error: implicit declaration of function 'fib_proc_init'
net/ipv4/fib_frontend.c: In function 'fib_net_exit':
net/ipv4/fib_frontend.c:1047: error: implicit declaration of function 'fib_proc_exit'
