serial: make 8250 timeout use the specified IRQ handler
The current 8250 timeout code duplicates the code path in serial8250_default_handle_irq and then serial8250_handle_irq i.e. reading iir, check for IIR_NO_INT, and then calling serial8250_handle_port. So the immediate thought is to replace the duplicated code with a call to serial8250_default_handle_irq. But this highlights a problem. We let 8250 driver variants use their own IRQ handler via specifying their own custom ->handle_irq, but in the event of a timeout, we ignore their handler and implicitly run serial8250_default_handle_irq instead. So, go through the struct to get ->handle_irq and call that, which for most will still be serial8250_default_handle_irq.
