    nimble/host: Fix EATT busy loop while waiting for credits
    
    If an EATT PDU could not be sent because the channel was busy with a
    stalled SDU, the wakeup event was queued immediately, which retried the
    send and requeued itself for as long as the peer did not provide
    credits. Only queue the PDU; it is sent once the channel is unstalled.
