Chen Wu 38011372cd fix: potential blocking code when call uart_wait_tx_done()
1. there is a risk of ticks_end overflow, if xTaskGetTickCount() plus ticks_to_wait is bigger than portMAX_DELAY
2. potential blocking code on waiting for tx fifo done. It usually occurs at esp uart uses flow control, and the other side of uart not.
