As per the previous patch, the own APIC instance is already available in
apic_msr_{read,write}, and can be passed along. In apic_mem_{read,write}, the
own APIC instance is available as the opaque parameter, since it gets registered
when initializing the io_memory attribute. As a result, no
cpu_get_current_apic() is involved any longer.
