[PATCH] disable_local_APIC() is only available when CONFIG_X86_LOCAL_APIC is defined

`disable_local_APIC' is only available when CONFIG_X86_LOCAL_APIC is defined :

arch/i386/kernel/crash.c: In function `crash_nmi_callback':
arch/i386/kernel/crash.c:153: warning: implicit declaration of function `disable_local_APIC'
arch/i386/kernel/crash.c: In function `nmi_shootdown_cpus':
arch/i386/kernel/crash.c:195: warning: implicit declaration of function `disable_local_APIC'

There may be a better fix, but the below seems to do the trick.
