Subject: [PATCH RESEND] mm, swap: delete meaningless __add_to_swap_cache() declaration

From: Miaohe Lin <linmiaohe@...wei.com>

Since commit 8d93b41c09d1 ("mm: Convert add_to_swap_cache to XArray"),
__add_to_swap_cache and add_to_swap_cache are combined into one function.
There is no __add_to_swap_cache() anymore.
