b4b657ba57 refactor: log `nEvicted` message in `LimitOrphans` then return void (chinggg)

Pull request description:

  Fix https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=49347

  LimitOrphans() can log expired tx and it should log evicted tx as well instead of returning the `nEvicted` number for caller to print the message.
  Since `LimitOrphans()` now returns void, the redundant assertion check in fuzz test is also removed.
