net: fib: fix incorrect call_rcu_bh()
After IP route cache removal, I believe rcu_bh() has very little use and we should remove this RCU variant, since it adds some cycles in fast path. Anyway, the call_rcu_bh() use in fib_true is obviously wrong, since some users only assert rcu_read_lock(). Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: "Paul E.
