Don't split req_ctx with ATR payload
The codnition for flushing a req_ctx on UART idle is fixed to flush only if 1) There has been no new data since last check, and 2) There are no req_ctx currently pending to be transmitted to USB, and 3) We did NOT just got a reset and waiting for ATR I saw an ATR split in two different req_ctx prior, presumably flush decided to send req_ctx after ATR but got a new character just before sent). If we did get a RESET, let original logic decide to send the req_ctx -- presumably when ATR data is fully received.
