Fix UART RX communication errors resulting in byte swapping.
Sometimes, the Half-Transfer Complete and Transfer Complete events execute in the wrong order. This happens when both the TC and HT bits get set before HAL_DMA_IRQHandler() runs. Don't know what causes that, but this mitigates the problem with a separate read index for the uart_rx buffer.
