x86/x2apic/cluster: Vector_allocation_domain() should return a value

Since commit 8637e38a ("x86/apic: Avoid useless scanning thru a
cpumask in assign_irq_vector()") vector_allocation_domain()
operation indicates if a cpumask is dynamic or static. This
update fixes the oversight and makes the operation to return a
value.
