[PATCH] kdump/i386: apic verification failure fix

o Removes the unnecessary call to local_irq_disable().

o Kdump was failing while second kernel was coming up. Check for presence
  of boot cpu apic id was failing in (apic_id_registered), hence hitting
  BUG().

o This should not have failed because before calling setup_local_APIC(), it is
  ensured that even if BIOS has not reported boot cpu, then hard set the
  prence of it. Problem happens because of usage of hard_smp_processor_id()
  which is hardcoded to zero in case of non SMP kernel. In kdump case second
  kernel can boot on a cpu whose boot cpu id is not zero.

o Using boot_cpu_physical_apicid instead to hard set the presence of boot cpu.
