ipv4: fib: Allocate fib_info_hash[] during netns initialisation.
We will allocate fib_info_hash[] and fib_info_laddrhash[] for each netns.
Currently, fib_info_hash[] is allocated when the first route is added.
Let's move the first allocation to a new __net_init function.
Note that we must call fib4_semantics_exit() in fib_net_exit_batch()
because ->exit() is called earlier than ->exit_batch().
