	    x86: update add-cpu_mask_to_apicid_and to use struct cpumask*

broke interrupt delivery on x2apic platforms.  As x2apic cluster mode uses
logical delivery mode, we need to use logical apicid instead of physical apicid
in x2apic_cpu_mask_to_apicid_and()

Impact: fixes the broken interrupt delivery issue on generic x2apic platforms.
