Don't call PageGetSpecialPointer() on page until it's been initialized.
After calling XLogInitBufferForRedo(), the page might be all-zeros if it was
not in page cache already. btree_xlog_unlink_page initialized the page
correctly, but it called PageGetSpecialPointer before initializing it, which
would lead to a corrupt page at WAL replay, if the unlinked page is not in
page cache.
Backpatch to 9.4, the bug came with the rewrite of B-tree page deletion.
