MEDIUM: fd: always wake up one thread when enabling a foreing FD

Since 2.2 it's safe to enable/disable another thread's FD but the fd_wake
calls will not immediately be considered because nothing wakes the other
threads up. This will have an impact on listeners when deciding to resume
them after they were paused, so at minima we want to wake up one of their
threads, just like the scheduler does on task_kill(). This is what this
patch does.
