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.
