hw/char/serial-pci-multi: Use qemu_init_irq_child() to avoid leak
The serial-pci-multi device initializes an IRQ with qemu_init_irq()
in its instance_init function; however it never calls qemu_free_irq(),
so the init/deinit cycle has a memory leak, which ASAN catches
in the device-introspect-test:
Direct leak of 576 byte(s) in 6 object(s) allocated from:

Use the new qemu_init_irq_child() function instead, so that the
IRQ object is automatically unreffed when the serial-pci
device is deinited.
