Revert "swiotlb-xen: pass dev_addr to swiotlb_tbl_unmap_single"

This reverts commit e7ba97ccef680a64b5c22f457267781c20211c5f.

This commit broke on x86 PV because entries in the generic SWIOTLB are
indexed using (pseudo-)physical address not DMA address and these are
not the same in a x86 PV guest.
