Dongli Zhang 53b29c3368 swiotlb: save io_tlb_used to local variable before leaving critical section ... When swiotlb is full, the kernel would print io_tlb_used. However, the result might be inaccurate at that time because we have left the critical section protected by spinlock. Therefore, we backup the io_tlb_used into local variable before leaving critical section.
