dcd/musb: restore EP0 OUT RXRDY flow-control comment
The pre-existing comment explaining why the OUT branch does not ack
RxPktRdy was dropped when the SETUP handling moved into
pipe0_start_setup(). It is load-bearing: acking before edpt0_xfer()
arms the drain buffer would let the host send data with nowhere to
put it. Restore it with the databook-deviation rationale so the
branches don't get "unified" later.
Review follow-up for #3643 (dcd_musb.c l.116 finding).
