x86, paravirt: Use native_halt on a halt, not native_safe_halt

halt() should use native_halt()
safe_halt() uses native_safe_halt()

If CONFIG_PARAVIRT=y, halt() is defined in arch/x86/include/asm/paravirt.h as

static inline void halt(void)
{
        PVOP_VCALL0(pv_irq_ops.safe_halt);
}

Otherwise (no CONFIG_PARAVIRT) halt() in arch/x86/include/asm/irqflags.h is

static inline void halt(void)
{
        native_halt();
}

So it looks to me like the CONFIG_PARAVIRT case of using native_safe_halt()
for a halt() is an oversight.
Am I missing something?

It probably hasn't shown up as a problem because the local apic is disabled
on a shutdown or restart.  But if we disable interrupts and call halt()
we shouldn't expect that the halt() will re-enable interrupts.
