thunderbolt: stream: Use polling with RX ring

The ring API already supports polling so that once there is anything in
the RX ring, it will mask the ring interrupt and call the ->start_poll
callback. This is the same mechanism that the USB4/Thunderbolt
networking driver already uses.

We can do the same for the USB4STREAM driver and poll any RX frames
while they are available, until we re-enable the ring interrupt again.
This provides better latency when the stream is in "normal"
(non-busy-polling) mode.
