MFC r229934:
Change the type of the paging_in_progress refcounter from u_short to
u_int. With the auto-sized buffer cache on the modern machines, UFS
metadata can generate more the 65535 pages belonging to the buffers
undergoing i/o, overflowing the counter.

To keep the layout of other fields of the struct vm_object intact
on stable/9, put enlarged paging_in_progress at the end of the structure,
and put a placeholder in the place of old pip counter.
