rp2/machine_uart: Fix read when FIFO has chars but ringbuf doesn't.
Prior to this fix, if the UART hardware FIFO had a few chars but still
below the FIFO trigger threshold, and the ringbuf was empty, the read
function would timeout if timeout==0 (the default timeout).
This fix follows the suggestion of @iabdalkader.
