KVM: PIT: stop vpit before freeing irq_routing
Fix:
general protection fault: 0000 [#1] PREEMPT SMP DEBUG_PAGEALLOC
......
Call Trace:
[<ffffffffa0159bd1>] ? kvm_set_irq+0xdd/0x24b [kvm]
[<ffffffff8106ea8b>] ? trace_hardirqs_off_caller+0x1f/0x10e
[<ffffffff813ad17f>] ? sub_preempt_count+0xe/0xb6
[<ffffffff8106d273>] ? put_lock_stats+0xe/0x27
...
RIP [<ffffffffa0159c72>] kvm_set_irq+0x17e/0x24b [kvm]
This bug is triggered when guest is shutdown, is because we freed
irq_routing before pit thread stopped
