Hua Zhong e6333fd4dd [PATCH] fix can_share_swap_page() when !CONFIG_SWAP ...

can_share_swap_page() is used to check if the page has the last reference.
This avoids allocating a new page for COW if it's the last page.

However, if CONFIG_SWAP is not set, can_share_swap_page() is defined as 0,
thus always causes a copy for the last COW page.  The below simple patch
fixes it.
