: Fix compiler error with CONFIG_PROC_FS=n

From: Johann Felix Soden <[email protected]>

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'

I'm pretty sure I merged in a change this morning which fixes this.

BTW, in general we do not put ifdefs into *.c code to fix stuff like this, instead we add empty implementations into a header file which is a better place for ifdef tests.

And that's how the patch which was merged handles this problem.
