This helps to further reduce the use of virt_to_phys and phys_to_virt functions. In order to clarify things since we now have 2 physical addresses in use inside of swiotlb_tbl_unmap_single I am renaming phys to orig_addr, and dma_addr to tlb_addr. This way is should be clear that orig_addr is contained within io_orig_addr and tlb_addr is an address within the io_tlb_addr buffer.
