Fix traversing to the deleted GIN page via downlink Current GIN code appears to don't handle traversing to the deleted page via downlink. This commit fixes that by stepping right from the delete page like we do in nbtree.
This commit also fixes setting 'deleted' flag to the GIN pages. Now other page flags are not erased once page is deleted. That helps to keep our assertions true if we arrive deleted page via downlink.
