[PATCH] i386 kexec-on-panic: Don't shutdown the apics.

It is dangerous to shutdown the apics in machine_crash_shutdown.

With my previous patch to initialize apics in init_IRQ we should be able to
boot a kernel without this.  As long as we reinitialize the APICs we don't
care what state they were in during bootup.

This should make machine_crash_shutdown noticeably more reliable.
