ipv4/fib_hash.c: fix NULL dereference

Unless I miss a guaranteed relation between between "f" and
"new_fa->fa_info" this patch is required for fixing a NULL dereference
introduced by commit a6501e080c318f8d4467679d17807f42b3a33cd5 ("[IPV4]
FIB_HASH: Reduce memory needs and speedup lookups") and spotted by the
Coverity checker.

Eric Dumazet says:

Hum, you are right, kmem_cache_free() doesnt allow a NULL
object, like kfree() does.
