Subject: [PATCH 1/6] x86/x2apic/cluster: vector_allocation_domain() should
 return a value

Since commit 8637e38 ("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.
