qemu_input_event_send() discards key event when the guest is paused,
but not the delay.

The delay ends up in the input queue, and qemu_input_event_send_key()
will further fill the queue with upcoming events.

VNC uses qemu_input_event_send_key_delay(), not SPICE, which results
in a different input behaviour on pause: VNC will queue the events
(except the first that is discarded), SPICE will discard all events.

Don't queue delay if paused, and provide same behaviour on SPICE and
VNC clients on resume (and potentially avoid over-allocating the
buffer queue)
