genapic's read_apic_id() returns the actual apic id extracted from
the APIC_ID register. And in some cases like UV, read_apic_id()
returns completely different values from APIC ID register.

Use the native apic register read, rather than genapic read_apic_id()
in verify_local_APIC()

And also, lapic_suspend() should also use native apic register read.
