hw/vfio: Use uint64_t for IOVA mapping size in vfio_container_dma_*map

The 'ram_addr_t' type is described as:

  a QEMU internal address space that maps guest RAM physical
  addresses into an intermediate address space that can map
  to host virtual address spaces.

This doesn't represent well an IOVA mapping size. Simply use
the uint64_t type.
