Mingqiang Chi 7b32fce06f hv:use spinlock_irqsave_obtain api for vpic ...

replace spinlock_obtain/spinlock_release with spinlock_irqsave_obtain
and spinlock_irqrestore_release to avoid dead lock for vpic module.

this vpic lock may be accessed in ISR context like this path:
  dispatch_interrupt->do_softirq->softirq_handlers
  ->ptirq_softirq->ptirq_handle_intx->vpic_set_irqline
