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.
