drivers/interrupt_controller: Add a timeout check on VT-D QI operation

QI operation are not supposed to last forever.
It's not an actual timeout based on clock, but a dummy counter instead.
That's because system clock might not have beed initialized yet, since
VT-D's init comes first (and that same init will use QI...)
