In case of static vector allocation domains (i.e. flat) if all vector numbers are exhausted, an attempt to assign a new vector will lead to useless scans through all CPUs in the cpumask, even though it is known that each new pass would fail. Make this corner case less painful by letting report whether the vector allocation domain depends on passed arguments or not and stop scanning early. The same could have been achived by introducing a static flag to the apic operations. But let's allow vector_allocation_domain() have more intelligence here and decide dynamically, in case we would need it in the future.
