[PATCH] i386/x86-64 disable LAPIC completely for offline CPU

Disabling LAPIC timer isn't sufficient.  In some situations, such as we
enabled NMI watchdog, there is still unexpected interrupt (such as NMI)
invoked in offline CPU.  This also avoids offline CPU receives spurious
interrupt and anything similar.
