Fix wrong keysize in PrivateRefCountHash creation.
In 4b4b680c3 I accidentally used sizeof(PrivateRefCountArray) instead of
sizeof(PrivateRefCountEntry) when creating the refcount overflow
hashtable. As the former is bigger than the latter, this luckily only
resulted in a slightly increased memory usage when many buffers are
pinned in a backend.

Backpatch: 9.5, where thew new ref count infrastructure was introduced
