Souptick Joarder 5326905798 xen/privcmd-buf.c: convert to use vm_map_pages_zero()
Convert to use vm_map_pages_zero() to map range of kernel memory to user
vma.

This driver has ignored vm_pgoff.  We could later "fix" these drivers to
behave according to the normal vm_pgoff offsetting simply by removing the
_zero suffix on the function name and if that causes regressions, it gives
us an easy way to revert.
