Kirti Wankhede 9e7b0442f2 vfio: Add ioctl to get dirty pages bitmap during dma unmap 
With vIOMMU, IO virtual address range can get unmapped while in pre-copy
phase of migration. In that case, unmap ioctl should return pages pinned
in that range and QEMU should find its correcponding guest physical
addresses and report those dirty.
