Subject: transfer: break the read loop when RECV is cleared

transfer: break the read loop when RECV is cleared

When the RECV bit is cleared because the response reading for this
transfer is complete, the read loop should be stopped. data_pending()
can otherwise still return TRUE and another read would be attempted.
