From: Matheus Tavares Bernardino <quic_mathbern@quicinc.com>

At e72a7f65c1 (hw: Move declaration of IRQState to header and add init
function, 2024-06-29), we've changed qemu_allocate_irq() to use a
combination of g_new() + object_initialize() instead of
IRQ(object_new()). The latter sets obj->free, so that that the memory is
properly cleaned when the object is finalized, but the former doesn't.

Fixes: e72a7f65c1 (hw: Move declaration of IRQState to header and add init function)
