[PATCH] mm/swapfile.c: Use helper function swap_count() in add_swap_count_continuation()

[Miaohe Lin]

Commit 570a335b8e22 ("swap_info: swap count continuations") introduced the
func add_swap_count_continuation() but forgot to use the helper function
swap_count() introduced by commit 355cfa73ddff ("mm: modify swap_map and
add SWAP_HAS_CACHE flag").
