hw/arm/smmuv3: fix eventq recording and IRQ triggerring
The event queue management is broken today. Event records
are not properly written as EVT_SET_* macro was not updating
the actual event record. Also the event queue interrupt
is not correctly triggered.
Fixes: bb981004eaf4 ("hw/arm/smmuv3: Event queue recording helper")
