drivers/serial: stm32: Revert change in uart_irq_rx_ready
In #31192 stm32 uart driver uart_irq_rx/tx_ready functions were
modified to take into account status of irq.
While it seems wlecome for TX (based on uart client's implementation),
this is not correct for RX.
Revert change in uart_stm32_irq_rx_ready function.
