Mark @fd as ignored so that the next call to gst_poll_wait() will yield
the same result for @fd as last time. This function must be called if no
operation (read/write/recv/send/etc.) will be performed on @fd before
the next call to gst_poll_wait().
The reason why this is needed is because the underlying implementation
might not allow querying the fd more than once between calls to one of
the re-enabling operations.
