The underlying `epoll_wait()` reports `EPOLLOUT|EPOLLERR|EPOLLHUP` on
the affected file descriptor, which `ext-uv` emits as an error code
`EBADF` with no events attached. We explicitly re-enable all active
events on this error event to invoke the writable listener for this
condition to match other event loop implementations and successfully
detect this as a refused connection attempt. All tests are now green.
