Michael Paquier 580b5c2f39 pg_buffercache: Fix memory allocation formula ...

The code over-allocated the memory required for os_page_status, relying
on uint64 for its element size instead of an int, hence doubling what
was required.  This could mean quite a lot of memory if dealing with a
lot of NUMA pages.

Oversight in ba2a3c2302f1.
