x86: Fix MSI-X initialization by using online_mask for x2apic target_cpus
found a system where x2apic reports an MSI-X irq initialization
failure:

... it turns out that when trying to enable MSI-X,
__assign_irq_vector(new, cfg_new, apic->target_cpus()) can not
get vector because for x2apic target-cpus returns cpumask_of(0)
Update that to online_mask like xapic.
