[PATCH 2/3] arm: kexec: fix the primary cpu passed to smp_shutdown_nonboot_cpus()

[Pingfan Liu]

kernel_kexec()->migrate_to_reboot_cpu() has already pinned the
reboot thread on either reboot_cpu or the first online cpu.

So machine_shutdown() should pass smp_processor_id() as the primary cpu
to smp_shutdown_nonboot_cpus().
